Corsair M75 Air review: Lighter than a cloud

Having the right mouse is arguably the most important thing to ensure when gaming - especially if you're particularly fond of competitive shooters like Counter-Strike 2 or VALORANT.

Your mouse is your aim in physical form, so having one that you feel in total control of can very well give you the edge you need to hit that round-winning headshot or awe-inspiring spray transfer.

Corsair is no stranger to the gaming mouse market, with a long history of widely used options - but the M75 Air looks to break into the upper echelon that is typically only occupied by mice like the Logitech G Pro Superlight or Razer Viper Ultimate.

Its key selling point - as the 'Air' in the name suggests - is its ultra-lightweight 60g frame, which takes it to the benchmark that the two aforementioned giants have set, but does it stand up amongst them and carve its own place in the top tier gaming mice space? Find out more in our full review below.

Floating on Corsair

While it might not seem like that much of a difference in principle, switching between the 60g M75 Air and my 74g Razer Viper Ultimate demonstrably showed the power that shedding 14g grams can really do to the feel of a gaming mouse.

I had no problems with the Viper Ultimate before trying the M75, but returning to it after testing Corsair's new mouse out felt sluggish and weighty, whereas the Air did in fact feel like it was barely there (in the best possible way.)

What this practically means when gaming is that quick flicks are far easier to achieve, and you gain a heightened precision over every action. While there are some small benefits to heftier mice like being able to hold your crosshair steadier, the general rule of thumb is that the lighter a mouse goes the closer it comes to aiming with just your arm, which truly lets your own mechanics shine.

I'm far from the best player when it comes to mechanics and aim in competitive first-person shooters, but when playing both CS2 and Rainbow Six Siege I did feel more confident in my actions and felt like I was able to be more precise and reactive when controlling heavy recoil and tracking moving foes.

This is also in part due to the impressive 26k MARKSMAN optical sensor which is able to accurately track even the quickest of flicks that you can pull off. While most flagship sensors from top brands like Corsair, Logitech, and Razer are excellent these days, it's still a fantastic sign that I didn't notice any inaccuracies when using the mouse and felt extremely confident that my actions would be accurately represented on-screen.

Build & design

One aspect that did disappoint me slightly, however, was the build quality of the frame. Of course, to achieve the ultralight weight that sits at the heart of the M75 Air you do have to make some build sacrifices and use lighter materials, but the materials used do feel relatively unspectacular for a mouse in its price range. It's not a huge deal, and it certainly doesn't compromise the experience, but it doesn't have that distinctly 'premium' feel in your hand compared to some of its rivals.

I have absolutely no complaints from a shape or ergonomic perspective though as the M75 would suit pretty much any grip from the more popular claw to my own personal palm grip. It's undeniably a right-handed mouse though, with a design that slants diagonally down to the left, and there are only the two additional mouse buttons on the left-hand side for easy thumb access. Overall, it's very comfortable to hold in my hand though, which only further contributes to the weightless feel and enhanced control when in use.

I did have some issues where the middle mouse button didn't always register, but this was a rare occurrence and the optical mouse switches felt incredibly precise, consistent, and tactile.

Brilliant battery life

One of the best features of the Corsair M75 Air in my eyes is the exceptional 100-hour battery life, which is top of the range for a mouse this light and makes the overall experience far more enjoyable.

There is no worse feeling than starting up a game and suddenly realising that your mouse is about to die, and having that crop up nearly every other day is something I have unfortunately experienced in the past.

However, the M75 Air really does last the 100 hours that is advertised, and I only had to change it twice during my entire testing period despite using it for both work and gaming. With no garish RGB draining the battery too, you can be sure that you're getting the full extent of each cycle after a full charge.

Supportive software

Having third-party software installed is never really preferable in my opinion, but the features on offer in Corsair's iCUE program do help soften the blow quite significantly. The mouse itself was incredibly easy to set up in the program, as all you need to do is insert the wireless dongle and turn the mouse on.

From there, you can tinker with the basic settings like DPI, polling rate, and more, before jumping into the more intriguing options on offer here. First up is a surface calibration feature, ensuring that the sensor is perfectly suited for whatever surface you're using the mouse on. As someone who uses a wool mouse pad most of the time, this was very much appreciated as it's far more textured than your standard cloth options.

What I really loved though was the option to create near-limitless Assignments for your mouse that essentially function like macros. Not only can you remap nearly every button on the mouse, but you can attach assignments like media keys, text inputs, and even button combinations to your mouse to make certain actions so much easier.

Escape From Tarkov is a game with an abundance of multi-button keybinds, so being able to apply my most used combinations to a single mouse press is incredibly helpful.

The Verdict

Overall the Corsair M75 Air is an excellent mouse that really can stand up against the most popular options on the market right now. It really does earn the association with air through its superlight frame, and the extremely strong battery life is truly a top selling point when it comes to wireless gaming.

While it would have been nice for the mouse itself to look and feel a little more premium, it's still a very comfortable device to use which only enhances your performance in the most mechanically demanding titles.

It's tricky to get people to move away from a mouse shape and feel that they are familiar with, but if you're looking to move into the premium gaming mouse sphere then I would definitely recommend the Corsair M75 Air as a brilliant option.
