Razer Basilisk Ultimate vs Cooler Master MM720: Mouse Comparision

The Razer Basilik Ultimate is undoubtedly the most efficient, designer, and most expensive mouse from the Razer brand. This mouse is recognized for its design, elegance, lighting, and wireless charging stand, which will adapt very easily to any desk. If we have to talk about Razer, it is not the mouse we think of first but the Chroma.

In a quest for a lighter mouse, the Cooler Master MM720 arises as a premium product. Indeed, with a weight of only 49 grams, Cooler Master manages to be even lighter than the Xtrfy M42, a mouse also with holes. Only, it is the shape of the Cooler Master MM720 that differs here from other gaming mice, with holes or not. But what is it really worth with this shape in width and not in length?

Elegance and performance are the keywords for this Razer Basilik Ultimate. We end up with a mouse with generous shapes and curves. Equipped with eleven buttons to configure your favorite macros and secondary functions via Razer Synapse. And, of course, like its wired variant, the Razer Basilisk Ultimate comes with the iconic multi-function trigger of the range.

The whole mouse is made of plastic. The mouse is made entirely of matte black plastic. The latter seems quite solid.

On the contact face of the palm, we find a very Razer design, accompanied by 6 buttons. We find them at the index and middle fingers and more precisely the left and right-click as well as its multifunction trigger which combines three clicks wheel, of course, programmable, the usual one, to activate the other clicks wheel, he will be able to shift the wheel towards left or right.

On the left side, there are 3 programmable clicks via Razer Synapse, plus a thumb rest. The three-click design allows it to be activated by the thumb without breaking the natural movements, which is a plus for long uses. The thumb rests on a non-slip matte black plastic.

We obviously have no button for the right part of the mouse, but we have anti-slip support.

Now let’s go under the mouse; we find 5 pads in 100% PTFE. Your mouse will glide over any surface thanks to the feet made of PTFE. It’s that white material used for high-end skates that everyone used to buy to improve their mouse glide, back in the days when they all used the cheapest material possible.

The advantage here is firstly the glide. Although the difference is not huge, it is possible to notice that the mouse glides just a little better than traditional material. Finally, the most important advantage is durability. These pads should scratch much less and, most importantly, should not come off.

Next, we will find a 2-port socket called ” Razer chroma mouse station,” allowing you to charge compatible devices and give your workstation more character.

Cooler Master sees things minimalist with this mouse. Relatively small, light product, which arrives in a box totally like the mouse, very compact. But this box of the Cooler Master MM720 is far from empty. We do not only find the mouse, but also several other elements, namely:

A set of grips
A set of spare pads
A disinfectant wipe

The Cooler Master MM720 adopts a rather specific shape because it is not a classic mouse like the Razer Viper 8K, for example. It is a mouse for gamers who play in Claw Grip. That is to say, with the whole hand on the mouse, positioned in a certain way. It is, therefore, quite possible to choose whether you want to put the grips on the mouse for better grip or if you want to keep the mouse natural to enjoy a different feeling.

Let’s take a look at the owner before looking at the rest of the bundle. The Cooler Master MM720 is an ultralight mouse weighing only 49 grams. The cable remains quite thick, but it is an illusion thanks to the braided over-cable. Inside, the electric cables are quite classic. However, this prevents damage to the electric cables if the mouse happens to have a few mishaps.

On the left, we can find buttons with re-assignable functions. They are practical and can easily be customized to use your favorite in-game features. On the top of the mouse, you can find the two main clicks, which are quite long in terms of the format of the mouse and its use. The Cooler Master logo is also placed behind it, without an inscription inside.

On the right side of the mouse, we have enough to accommodate the ring finger on the mouse and the little finger on the edge, which goes hand in hand with the use of the latter.

As you will have noticed, there are holes on both sides of the Cooler Master MM720. Small holes and more small holes, numbering 178 on this mouse, allow you to free up weight and obtain the 49 grams expected and promised. The mouse is also available in four colors, namely:

Shiny black
Matte Black
Brilliant white
Matt white

Of course, everything is RGB and controllable via the brand’s software, just like many other features. We find RGB in the mouse, which is inevitably visible thanks to the many holes with which it is equipped, but also at the level of the wheel. Another small detail that is very important, the mouse is IP58 certified; in other words, it is dust and splash-resistant. It is practical and essential with components in the open air to resist a sweaty hand ready to win on Valorant or CS: GO and the various dust that can enter it freely. However, it doesn’t have any holes underneath, which is a plus point.

Cooler Master takes it a step further by stating that it can wash the mouse underwater. This doesn’t mean that you can put it in the dishwasher, but that, in theory, it can run under running water and dried before preferably being plugged back in. 


The Razer Basilisk Ultimate is equipped with a charging dock equipped with the Razer Speedflex USB -C cable. This is a somewhat peculiar braided cable that Razer has been using on their mice recently.

Indeed, the Speedflex cable is braided a little more loosely, and the rubber cable inside the braiding is thinner than what can be found traditionally. Braiding, therefore, provides real protection here, unlike that used on more conventional rubber cables, the latter often being thick enough not to need additional protection.

Added to the thinness of the cable, the rather loose braiding gives a very flexible result, much more than what can be found in the competition. However, the cable is a bit thicker and therefore may not be suitable for all media. But once in place, you won’t need to move it anymore.

The sensor of this Razer Basilisk Ultimate is a Razer Focus + Optical Sensor, an excellent optical sensor. The device can go up to 20,000 DPI, which is more than enough for any style of play, if not too high. However, this allows better precision even at lower sensitivity.

As is customary with Focus + sensors, no stall problem is to be reported. The sensor is precise, responsive, and does not suffer from excessive acceleration.

Cooler Master MM720- The switches are guaranteed 70 million clicks in terms of performance, which still leaves a certain amount of time for the mouse to use. For example, it can display up to 400 fps, so it will be perfect with an Asus 360 Hz screen and will not be a limit at very high frequencies.

The mouse’s frequency (or pooling rate) is 1000 Hz, which allows a response time of 1 ms without worries; it is a standard on gaming mice, except with certain competitors who offer even higher frequencies. However, the difference is not really obvious, and apart from a few models, most mice are at 1000 Hz.

It can withstand accelerations up to 50G, which is also standard in this kind of mouse. We did not manage to win it once, despite our multiple attempts. You can therefore move it at will without risking this kind of inconvenience. This is obviously thanks to its sensor, a PixArt PMW3389, which is found on many models in this range and sometimes even more expensive models. This sensor is recognized and reputed to be flawless, which will therefore serve to give you confidence in its performance.

This PixArt PMW3389 has a sensitivity amounting to 16,000 DPI. Granted, you won’t always be playing at 16,000 DPI, if not very rare, but it’s still interesting. Generally, when I play CS: GO, I settle on 4500 DPI, which is already very good. However, it differs depending on the games you will be playing.

Back lighting

Since this is a Razer product, the Razer Basilisk Ultimate obviously has a lot of lighting. On this mouse, we have no less than 14 programmable LEDs.

From its optical side, we expected the click to be a little quieter than usual, but here it is not. The audible feedback is as satisfying as the haptic feedback, albeit a bit noisy.

The notches of the wheel are adjustable on the mouse. This allows you to tailor the settings precisely to your use. Finally, the side buttons, although of lower quality than the main clicks, are quite good. They are totally usable without frustration.

The Cooler Master MM270 has two backlight zones. One is located inside and allows to illuminate the contours of the logo but also the inside of the mouse. The other is located at the dial level and allows the backlighting of the dial-in almost its entirety. Indeed, the front part of the latter, the farthest from you, is not very well backlit. Never mind, this is not the part that you will see the most, and it remains a small detail on the whole of this pleasant MM270.

The device is customizable via the Cooler Master MasterPlus software, the driver for the brand’s products.


The available and downloadable software here allows 100% management of all the settings of this device. You will notice that the software immediately recognized the mouse. The home page lets you find all the brand’s devices connected to your PC, starting with the Razer Basilisk Ultimate.

A synapse is software very provided in functionalities and integrations. Sometimes even too full, to the point of being one of the heaviest drivers on the market. However, most of the features may not be installed, so if you want to save some space on your disk, feel free to look at the installation settings.

Cooler Master Plus is the brand’s software that allows you to tame all the manufacturer’s devices. If it is indicated several times that it is available in English, rest assured, it is also available in French.

It is possible to create personalized profiles for each game you will play within a certain limit, of course. However, the profiles can be started automatically with the games, which eliminates the need to change them manually and is very practical. In these profiles, you can change the sensor’s sensitivity, the assignments of the different mouse buttons, and the backlighting effects. So, GTA may have different settings from your favorite FPS.


The Razer Basilisk Ultimate is a perfect performance gaming mouse with a remarkable wireless charging system. The sensor is good, as are the switches. If you don’t mind an asymmetrical design and a heavier-than-standard mouse, the Razer Basilisk Ultimate Mini is for you.

The Cooler Master MM270 stands out for its shape, of course, and it’s very lightweight against mice like the Xtrfy M42, for example, with 20 grams less! Despite its small size, it ensures worry-free and the grip, if it is different from a “classic” mouse, comes very quickly during use.


Corsair M65 RGB Ultra Optical Gaming Mouse Review

Corsair M65 RGB ULTRA is the latest addition to the Corsair mouse stable. This model is also a real concentrate of technology, designed for those looking for something heavier (precisely concerning weight) than those that Corsair has recently launched. But weight isn’t the only detail that catches the eye. 

Excellent build qualityStiff cable
8 programmable buttonsExpensive
Up to 8,000 Hz of Polling Rate
26K DPI sensor

Corsair M65 RGB ULTRA is a mouse with extremely peculiar shapes. Its structure is designed only for right-handed users since both the programmable buttons and the side shapes are precisely designed for use with the right hand. However, a form factor that fans of the brand and the M series will recognize and appreciate.

The M60 model made its debut in 2011, 10 years ago. From the first minutes, however, the hand, at least ours, is at ease. Each finger finds its place, and even those who use the artisan grip will have no problems of any kind. It may be a little lower than we would have expected, but we did not encounter any fatigue or other issues related to prolonged use. As usual, the device accompanied us for several days, not only in gaming use but also in work, to allow us prolonged tests involving the use of software and video games.


Corsair M65 RGB ULTRA hides many other essential features. The body below, which glimpses out from the front and back, is in aluminum. The resistance of the product is therefore out of the question. The upper layer is made of plastic, pleasant to the touch, and not too smooth, just enough to guarantee a sufficient grip. To increase the grip, there are also the lateral knurls where the thumb and little finger rest.

As mentioned in the introduction, Corsair M65 RGB ULTRA is a mouse that boasts, unlike the many coming on the market lately (as well as Corsair’s Saber PRO RGB Wireless ), a weight that can even exceed 100 grams. It weighs 97 grams, but in the back, the one that houses the sensor, so to speak, it is possible to insert three additional weights that allow you to go up to 115 grams. The peculiarity then is not only the fact of inserting these three weights but also arranging them differently or using only one or two of them to create one’s balance. And the way to balance the mouse is also helpful for another feature that we will discover shortly.

There are two more programmable buttons before the mouse wheel, useful for cycling between DPI configurations. The wheel is huge and has a “tire” style cover that guarantees excellent grip. The feedback of the button integrated in the wheel itself is more than discreet. A few technical hints before continuing further. The main buttons are the CORSAIR QUICKSTRIKE that we had already appreciated in the SABER PRO RGB Wireless review combined with switches OMRON optics , designed to guarantee a practically instantaneous speed of implementation. The two buttons can be pressed along their entire structure. The smoothness of the mouse is guaranteed by 4 classic PTFE feet that follow the particular structure of the aluminum body. 


Here we have the wired variant of Corsair’s new M65 RGB ULTRA. Also, in this case, we are dealing with a long cable (1.8 meters) in Paracord. It’s like not having it. The cable runs smoothly over the mat or surface where you would usually use the mouse without hindrance. Indeed, it is precisely the presence of the cable that allows a polling rate 8 times higher than that of most gaming mice. Usually, due to the reviews, we alternate the use of wireless mice with wired ones. We assure you that the transition to those with Corsair Paracord cable is painless.

The Corsair AXON Hyper-Processing proprietary technology allows the achievement of the 8,000 Hz polling rate (the same reached by the wired version of the wired SABER PRO ). But be careful: the 8,000 Hz mode can only be activated by the iCUE software and only if you have sufficiently performing hardware. Thanks to the Corsair MARKSMAN proprietary sensor, 26,000 DPI of sensitivity can be reached, an exaggeratedly high value that you will hardly find yourself exploiting. What matters is that the sensitivity can be increased by 1 DPI at a time, allowing, obviously again via iCUE, to see your reference values ​​(even for the Sniper button).

The weight balance of the mouse is also linked to another feature of the M65 ULTRA. Among the many integrated hardware improvements, there is also the so-called Sensor Fusion Control, which integrates a 6-axis accelerometer and gyroscope. The two sensors have a dual purpose: the first is to improve the tracking of the repositioning of the mouse in case you lift it from the surface; the second is to allow you to match the functions of the mouse to the inclinations. Also, from iCUE, it is possible to calibrate inclination of 20, 30, or more degrees towards one of the 4 directions (left, right, front, back) and match these inclinations to specific functions. For example, you could make tilting the mouse 20 degrees to make the system respond as if the user were pressing the V key on the keyboard. You can even match whole text strings, maybe a specific message to send in the game chat.

A feature that is particularly difficult to find in other mice adds to the already excellent hardware equipment available to this M65 RGB ULTRA. When we said that it is a real concentrate of technology, we were not joking at all. An obligatory mention also to LED lighting. Since, in this case, Corsair did not have to spare itself to keep the weight within particularly low thresholds, many more LEDs have been integrated, which contributes to making the mouse even more aggressive and iconic. 


Without CORSAIR iCUE software, you do not have access to most of the top features of the mouse in question. We still find it a bit immature and complicated. Still, if nothing else, connecting M65 ULTRA and opening iCUE, you are greeted by a series of tutorials that explain step by step how to set, for example, the functions related to the inclination, how to assign new keys, and how to manage the lighting. The process to calibrate the mouse on the surface of use is also very useful, an essential step to use M65 ULTRA to the best of its possibilities. 


Corsair M65 RGB ULTRA is one of those mice that, at first glance, might seem almost niche. The truth is, it’s effortless to fall in love with it. Under the fine aluminum body hides the best of Corsair’s proprietary hardware, which allows access to some particularly original features and, in some cases, really comfortable.

The SNIPER button will delight shooter lovers, as well as the 26,000 DPI sensor that allows sensitivity shots of 1 DPI at a time. However, note that not everyone needs so many options, programmable keys, and such high performance. The price is not affordable for all budgets, especially if you want to opt for the wireless model. But know that the wired gets along great.

Steelseries Aerox 3 vs Aerox 3 Wireless: Light Weight Mouse

Steelseries Aerox 3 and Aerox 3 Wireless are two almost perfect mice that combine suitable sensors with the high build quality. However, they have a notable problem that can be crucial.


Pros and Cons

Aerox 3Aerox 3 Wireless
Awesome build qualityAwesome build quality
Griffy surfaceGriffy surface

Slightly stiff cableWeak battery life

Steelseries Aerox 3 and Aerox 3 Wireless are identical in both exterior and use. We have a lot to write about Aerox 3 and the features that make them stand out in the market. However, both fall on the finish line due to a simple detail that we usually take for granted: the feet are too thin, which leads to the chassis rubbing in soft mouse pads if we are not very light with the hand. With better feet, Aerox 3 would have been a given recommendation in Mouse Guide.

  • TTC Golden Micro switch instinctively tactile click
  • Flawless TrueMove sensors
  • Well-balanced shape and ambidextrous
  • Size: medium
  • Suitable for most grips

Both variants Aerox 3, are identical in appearance, down to millimetres in dimensions. For that reason, we will describe Aerox 3 and Aerox 3 Wireless together in the future, provided that there are no differences between them.

Aerox 3 has a stylish and symmetrical design with a tasteful accent in the logo on the left mouse button. In true super-light fashion, most of the top and bottom of the mouse is equipped with diamond-patterned holes to trim down the weight.

Aerox 3 is relatively neutral in its form and is suitable for more hands than, for example, the competitor Superlight from Logitech. There are no aggressive features in the case. It is neither high nor low, the click is not too hollow or too flat, and it is neither too long nor short. The sides are also almost straight except for the bottom curve. Steelseries markets the mouse for claw and fingertip grips, but our tests have no problems with palm grips. Thus, we see that the vast majority of hands can find a comfortable grip.

From a construction quality perspective, we have nothing to complain about. Aerox 3 is a robust mouse that is rattle-free and crack-free when we hug it. Despite a Bluetooth module in the rear half of the wireless variant, the weight is evenly distributed when we hold it in the middle with the index finger and thumb tips.

The mouse has an unusually grainy surface texture that is not comparable to other mice we have tested so far. Most matte mice usually have a fine-grained or smooth texture, but Aerox 3 has unusually coarse grains. This is not sandpaper or discomfort when used. We have no preference and do not mind the slightly coarser grains, and for those users who want a grippy mouse, Aerox 3 can be a good choice.

So far, it has been a top-class mouse, but unfortunately, it falls entirely on one detail. The feet are so thin and the surface so small that if we rest our hand on the mouse, it starts scratching on soft mousepads. The problem is challenging to fix on your own with aftermarket feet because the sensor has a compact lifting length. It leaves the option of sanding down the bottom of the mouse, something we should never even have to think about in the premium segment. The material is PTFE, but Steelseries does not claim that they are made of pure Teflon, unlike many competitors in the market.

If you are looking for a wireless mouse but went for the Logitech G Pro X Superlight due to the lack of LEDs, Aerox 3 may be a good option. In addition to a LED diffuser at the bottom, light also leaks through the chassis. We guess that the diffuser is made of the popular material polycarbonate and that the bottom has a cut-out to let the light through. In actual use, the light nicely reflects in our mouse pad via the light loops.

The cable is too stiff for our taste. It is still far better than a standard rubber hose cable, as in the Logitech Superlight. In both Superlights and Aerox 3 Wireless cases, the mice escape criticism as they are intended to be used wirelessly. Aerox 3 uses at least one USB-C port, making it easy to switch to an aftermarket cable, a feature that Superlight does not share.

According to the specifications, the battery life is up to 200 hours during constant use, emphasising “up to”. We have a hard time getting a charge to last 50 hours. Compared to the Logitech G Pro X Superlight, which we could use for several weeks without charging, we can make the Aerox 3 Wireless live for about four to five days with equivalent use. Fortunately, the mouse is fully charged in about 45 minutes.

Aerox 3 weighs 58 grams, and 68 Aerox 3 Wireless weighs 68 grams, 1 gram more than the official specifications.


It is always interesting and exciting to test mice that do not use the otherwise popular Omron switches. There is nothing wrong with Omron switches but a slight variation does not hurt. Aerox 3 uses TTC Golden Microswitches.

The switch’s weight feels noticeably heavier than the popular Chinese Omron D2FC-F switches, which abounds on today’s market. They are also more tactile, which emphasizes the importance but results in a crispier click. In terms of sound, they are much louder than Omron switches, while the sound is louder. In summary, the controls are of a high class and are an excellent alternative to Omron switches for the user who wants a more distinct tactile feel.

The scroll wheel sits low and has a tactile click, well-defined steps and is relatively loud. We prefer this type of scroll wheel compared to those higher up and have slightly spongier measures. In this case, we can compromise on the sound level.

The side buttons are also distinctly tactile, but they are narrow. The narrow design can make it difficult to feel the small space between the front and back side buttons. Despite this, we have not encountered any problems where we accidentally press the wrong side button. It is still good to know if you prefer side buttons with a larger and broader area.

We have always disliked having CPI control buttons on the top of the mouse. We do not see any scenarios where we often need to change CPI and therefore prefer to have these at the bottom of the mouse, where we never happen to access them by mistake. That said, the CPI slider is of unusually high quality. It is usually a forgotten detail, which results in a spongy click, but in Aerox 3, it is a highly tactile and qualitative click.

Today’s high-performance sensors are usually identical. Performance rarely differs in actual usage scenarios. What can distinguish high-performance sensors is often related to small posts on specification sheets. Sometimes there are manufacturer adaptations of market-leading sensors that are worth keeping an eye on. The impressive thing for us is if there are any deviations. In this segment, the focus is less on sensors. It would help if you instead chose mouse by mouse shape.

Sensor performance

Aerox 3 uses the SteelSeries TrueMove Core sensor, while Aerox 3 has TrueMove Air. Interestingly, they do not share the sensor. In terms of specification sheets, TrueMove Air is the better sensor. In actual use, today’s sensors are so good that we do not notice any difference.
We have nothing to complain about other than that the lifting length is slightly shorter than, for example, PixArt sensors, which may explain why the feet are so thin. In our opinion, a quick lifting length is not negative, provided that the feet that the mouse is equipped with do not need to be upgraded.

We use MouseTester 1.5 to collect sensor data. We then review the results for any deviations. We find no traces of the common culprits in today’s mice, which inferior sensors have difficulty with: namely, Angle snapping, jitter and other compensations.

CPI – counts per inch
Manufacturers always have self-specified tolerances to adhere to. This means that the stated CPI does not always correspond to what the consumer expects. There is a built-in calibration for CPI in Mouse tests where we give the mouse a specific length and get back a number. The returned number should correspond to the set CPI on the mouse.

Jitter test
Jitter means that the motion tracking is inconsistent. We test it by moving the mouse diagonally and slowly to see if a step is formed instead of a soft line.

Tracking speed
Some mice may have difficulty tracking fast movements correctly. We move the mouse quickly over a surface and note the speed curve on the result. The result should not be zero or have unexpected consequences.

Angle snapping
By drawing fast circles with the mouse, we can see if it catches up or falls back and begins to compensate by drawing straight lines.

Lifting length
Players with low mouse sensitivity may need to lift and reposition the mouse during active play. Therefore, it is essential that the mouse has a short lifting length and stops reading movements almost immediately. We use actual user scenarios when we test lift size because it is difficult to get exact numbers.

We must always consider the human factor in this type of test. MouseTester can provide data to go on if we feel that something is not quite right. However, they are not absolute. What counts in the end is how the sensor performs and how it is experienced during actual use.


Aerox 3 uses the Steelseries Engine 3 software, which has expected features. These are macros, adjusted CPI and various LED functions. What shines with its absence is an adjustment of the lifting length.

Two features that we recommend to stay away from are Angle snapping and acceleration settings. The Angle snapping setting locks the pointer according to the grid and follows them instead of letting us point freely and precisely. The acceleration settings create lag. During specific movements, the lead slows down or increases in speed without corresponding to our actual mouse movement.

Steelseries Engine 3 is relatively resource-efficient and does not need to run after the settings are configured.


The SteelSeries Aerox 3 and the Aerox 3 Wireless features a different sensor than the wireless version. The Wireless has a considerably greater CPI range and a shorter lift-off distance, which results in fewer unwanted movements while moving the mouse. Despite having an internal battery, it is only slightly heavier than the cable version. Its wireless connection and multi-device pairing capabilities make it more suitable for usage in the office and on the go. The Wired features less click latency and higher build quality.

Trust BAYO Ergo Wireless Vertical Mouse With RGB Light

The Trust brand, identified with gaming equipment, decided to try its hand at the ergonomic mouse market, and this is how the Trust Bay model was created. It has RGB lighting. So let’s check what the company has prepared for us because it has prepared quite a lot of good things on paper.

Comfortable to useNot suitable for left-handed
Neat and resistant designThe battery cannot be replaced
RGB light on the thumb rest
Good button response

The Trust has recently undergone a small image change because the usually black and red packaging, of course, heralding gaming equipment, has now been replaced by white and orange.

However, apart from the visual issue, a simple cardboard box with a front render, corresponding to the size of the product itself, has a lot of goodness in it. A lot, because in addition to a mouse and papers wrapped in foil, we get a tiny 2.4 GHz USB receiver and a more than 80 centimeters long USB-A to USB-C cable. Unfortunately, it is only used for charging because Trust Bayo does not support wired mode.

  • Unknown optical sensor 
  • Sensitivity on 5 levels: 800, 1200, 1600, 2000, 2400 DPI
  • Main switches: Huano with 20 million click durability
  • Number of buttons: 5 + scroll wheel 
  • Interface: wireless via 2.4 GHz USB receiver
  • Built-in rechargeable battery
  • USB refresh: 125, 250, 500 and 1000Hz
  • RGB backlight on the base
  • Warranty: 2 years

The Bayo Trust doesn’t discover America, to be honest. The manufacturer focused on the traditional shape of this type of mice, shortening the casing a bit so that my larger hand does not fit perfectly on it because the fingertips “go beyond the main buttons. However, this is not a product defect, and my private problem is that smaller hands (especially feminine) will find themselves on the Trust Bayo body without any problem.

Speaking of the shape, the Trust opted for a five-element housing, combining individual parts in such a terrible way that the gaps between the plastics created will be dreamed up long after nights for me. Especially that the plastic used, although quite pleasant to the touch, is not of the highest quality and gets dirty quickly, which is not a problem in the case of the gray material that builds the buttons. There, the material makes a much better impression, and together with a modest insert on the base, it also improves the overall visual aspect of the Bayo model.

However, it is difficult to call this mouse a work of art, but you cannot be tempted to say that it is badly designed. The flaws in its design are economical, and all because Trust Bayo combines wireless mode, an unusual housing format, full mouse capabilities, a modern USB-C connector, and a built-in battery. In other words, keeping the price below $40, the manufacturer had to save and fell on the materials used, the production process, and the optical sensor of unknown origin.

It is a pity that at the same time, Trust added a simple RGB backlight to the model, straining the budget on the mouse and functionally fulfilling only the role of a warning about the low battery. This backlight may not look bad, but it stings the eyes a bit because it is not only there but also significantly complicates the base of the mouse. It includes a sensor and a simple on/off switch with an additional mode that turns on the backlight and the button itself to change the backlight mode.

Simple sliders complement the whole with (interestingly) rounded edges and a gap for a USB receiver. However, do not try to pull it out with your fingers; there is no need – just hit the mouse lightly on your hand in the air, and the receiver will “fly-out” by itself.


While unusual, the Trust Bayo features a traditional set of buttons (two main, two sides, roller), completed by around a simple button on the spine to change the sensitivity. These buttons work. on average, but there is nothing to be bothered about because they will be perfect for office use. Especially since their arrangement for smaller hands will not be any problem during work. 


The manufacturer does not mention something officially and broadly in the presentation of the product, it is a disadvantage. In Trust Bayo, this something is an unknown optical sensor, which due to the lack of software, is doomed to operate at the levels of 800, 1200, 1600, 2000, and 2400 DPI. We change these levels using a dedicated button on the back, and as far as precision is concerned, it’s wrong. So bad that even the software was unable to make the appropriate measurements because of the signal inconsistency.

Trust Bayo is tormented by a whole inventory of known errors in the operation of sensors in mice, ranging from increased prediction, interpolation, and high-frequency jittering at the level of 800 DPI, as well as negative and positive acceleration. In general, therefore, playing games with Bayo that require precision is a chore, and working on tasks requiring precision should not be a special problem in office applications.


A wireless vertical mouse for under $40 should immediately light a red lamp in our heads. However, this does not mean that Trust Bayo is a completely useless model that will not find a niche for itself. This mouse is designed to work for those who suffer from wrist pains when using standard “flat” models. It may not be the best made, its materials could have been better, and the sensor could be more precise, but by choosing this model, you get wireless equipment with a built-in battery, and if you are looking for these two features at this price, Bayo will be a good choice.
