Review: Corsair M75 Wireless



It’s time to take Corsair’s M75 Wireless in hand and give you our impressions of it. We’ve used it for gaming, browsing and office work. What did we think? Find out now!



Corsair’s new mouse is easy to grip, with the fingers sliding naturally over the various slots. Indeed, as a right-handed user, my thumb automatically moves to the left of the mouse, where the buttons are located. Similarly, my index and middle fingers come to rest on the left and right clicks respectively. Finally, my ring and little fingers are positioned on the right, below the buttons. Seeing the buttons on the right-hand side, I was afraid to use the mouse without seeing them. In use, I found this was not the case at all. They’re quite slim, and unless you really force the mouse, you won’t operate them, unlike Thermaltake’s Level 20 RGB mouse we tested a few years ago.

In the same vein, once again we appreciate the absence of gutters that direct the fingers and can get in the way when using the mouse. We’re thinking in particular of the Corsair Ironclaw mouse, which was a very “guided” model that didn’t allow much freedom.

Here, the M75 Wireless is designed more for claw grip and palm grip . These will be the most pleasant and suitable. Finger grips are also possible, but are more suitable for people with large hands.

The best thing about Corsair’s new mouse is that it’s totally ambidextrous, so it can be used by right- and left-handed users alike. This is quite rare (compared to right-handed models, anyway) on the mouse market, so it’s great news! However, the button for changing DPI is located on the underside of the mouse. In the event of an emergency during video games, for example, it will be difficult to change them quickly and easily.

On a personal note, I find that the scroll wheel on this model is a little softer than on my everyday mouse (MSI Clutch GM41 Lightweight Wireless), and will tend to stay depressed if you press a little “hard” on it. It’s also less pronounced and, in my opinion, less pleasant to use.

What’s more, Corsair indicates that this is a lightweight mouse, with a little ” lightweight ” on the box. Nevertheless, in my opinion, 89 g is heavy for a lightweight mouse at the moment. If you compare it with the competition, such as Lift 2 Ergo (61 g), Lift 2 Symm (58 g), Model O (67 g), Harpe Ace (54 g) or Clutch GM41 Lightweight wireless (74 g), it really starts to feel heavy! In my opinion, it’s a relatively classic weight for a mouse.

On the other hand, a good point for Corsair’s new mouse is that it doesn’t mark fingerprints at all. That’s a good thing, especially if you spend a lot of time in front of the computer and tend to use moisturizing hand cream, for example.

A quick word on the autonomy of this model: the M75 Wireless has a very interesting battery with an estimated autonomy of at least 120 hours. Suffice to say, in ten days of testing, we couldn’t have put it out of its misery!

The sound of the M75 Wireless buttons:

Once again, we’re dealing with a relatively quiet model with a rather dull sound as far as mouse clicks are concerned. In use, it’s much quieter than a Corsair Harpoon RGB Wireless, for example.


Here, unlike the competition, there’s something to be said for the glide of this M75 Wireless model. Like the Lift 2 Ergo and Symm, the presence of large PTFE pads at each end will tend to slow down our mouse when used on a fabric mouse pad. Unlike the MSI Clutch GM41 Lightweight Wireless or the Model O, which have 6 smaller pads. I found this very unsettling at first, especially for manipulations requiring great precision, such as object selections on Photoshop in my case.

The RGB on Corsair’s M75 Wireless is very neat. Indeed, the two large LED strips running up the middle of the mouse are very aesthetic and diffuse the light well. However, the RGB does not go all the way to the top of the groove. This gives a “poorly finished” effect and is a bit of a shame. Otherwise, the logo is also illuminated, as is the underside of the M75 Wireless. It’s a nice touch, as the light spreads over the mouse pad.

Colors are also clearly visible. Whites stand out well, while yellows are also true to form, as are blues.
