Corsair M75 wireless mouse review: Smooth as silk

Corsair is a well-known and trusted brand for making internal PC components, but how does their new M75 wireless mouse hold up in a fiercely competitive market?

Corsair is one of the most well-known brands in the field of PC components and accessories, producing solid and hard-wearing devices such as the Corsair HS80 MAX headset or the elegant K65 keyboard. The gaming mouse market is a tough one, however, with a lot of excellent competition. Can the new M75 Wireless mouse hold up against other gaming mice in its class?

Design

The Corsair M75 Wireless comes in either a black or white colorway and visually looks very similar to the M75 Air that came before it. The mouse has a matte finish that is quite nice to grip without needing any rough texturing and avoids the trap of being too smooth and slick to hold properly. The buttons feel crisp and the scroll wheel is clicky without sounding or feeling loud or obnoxious.

The design is symmetrical, with thumb buttons on either side allowing for ambidextrous use. It has a domed shape that feels comfortable for palm and fingertip grip, and it is actually hard to find a position that isn’t comfortable.

The lighting on the M75 is Wireless is pleasantly subtle, with two little stripes on the side and through the logo. It is actually fairly bright and vivid, clearly visible even in bright daylight next to a window it doesn’t get washed out at all. It’s the right level of stylish without being garish.

The location of the pairing button and the DPI button underneath the mouse is less than ideal. Locating the pairing switch somewhere out of the way makes sense, but the DPI switch less so. This is somewhat lessened by being able to adjust the DPI in software, but it still isn’t ideal.

Some users will not be keen on the weight of the mouse, which at 89g is substantial compared to many others on the market like the Glorious O2 wireless or a Logitech G Pro X Superlight. Despite this, it didn’t feel overly heavy, and in fact the feeling of substance provided a feel of sturdiness and quality. That said, it probably wouldn’t be suitable for those who need an ultra-lightweight mouse for whatever reason.

Though a white version has been tested, no discoloration appeared at any point and it still looks brand new.

Features

The M75 can connect using Bluetooth, 2.4Ghz wireless, or via the included USB cable. The dongle for the wireless is helpfully included in a little storage nook underneath the mouse and is probably the best option for connection if you have a spare USB port. The Bluetooth is functional, but not as solid or smooth as the 2.4Ghz connection, but that is an issue with Bluetooth in general. The included USB cable is quite long, though does have a nice braided outside and feels fairly high-quality overall. The ambidextrous layout of the mouse gives you a total of four side buttons, which are all programmable, and the physical buttons can even be removed and swapped out if necessary.

On a more tangible level, the little PTFE mouse feet glide wonderfully over almost any surface and are fairly resistant to picking up dust and debris, making for a headache-free experience.

The software is great

One of the major features of the M75, as with most Corsair products, is compatibility with the iCue software. This is software that is simple to download and install and comes with a range of useful features. By default it will report the results from your hardware sensors, showing the temperature and load of your processor, RAM, and GPU, already a useful function for PC gaming. The iCue software also allows you to configure the mouse to your liking, changing the style of the RGB lighting, or setting the DPI profile and allowing you to program the side buttons for macros or other functions.

Corsair’s iCue software is fairly mature as a product now, so it is pleasingly easy and intuitive to use. You can even set up multiple profiles for various different use-cases. Thankfully, iCue is fairly clean and lightweight and takes up fewer system resources compared to something like Razer Synapse.

You will need to use the Hyperspeed dongle and pair the mouse using the iCue software if you want to take advantage of polling rates over the standard 1000Hz, this will take up one of your USB slots, but if you need that level of performance, its a small price to pay.

Gaming Performance

If you want to put a mouse through its paces, then an ARPG hack-and-slash where the mouse controls almost everything is a decent place to start. Having just picked up Last Epoch, that seemed like a great idea for a testing ground.

The M75 performed flawlessly, with no sign of any lag or double-clicking, even when the buttons were being hammered in a boss battle. The cursor was always exactly where you expected it to be. It was the same story in Lethal Company. The mouse did exactly what it needed to, and felt supremely comfortable the entire time.

Other people using the mouse commented that they felt that the side buttons were in slightly the wrong place to feel comfortable since they are slightly inset, but with my tiny hands, it never felt that way in my grip.

Battery Life is phenomenal

Even with the RGB turned on, the M75 lasted a good few days on 2.4GHz wireless before it complained about needing a charge, though enabling the 8000Hz polling does cut this figure down a bit. I can easily imagine it would be capable of going the advertised 100 hours plus if the RGB was disabled.

Should you buy it?

The Corsair M75 is somewhat pricey compared to many other wireless mice, and it doesn’t do anything completely revolutionary. Fans of lightweight wireless mice won’t be satisfied with how much it weighs, and those looking for a budget option will be better off looking at the M75 wired counterpart, which is much cheaper at $79.99.

It is still a brilliant mouse with some great flexibility. It is comfortable, well-designed, responsive, and feels solid in your hand. It could perhaps stand to be a little cheaper but is a great option for someone who wants a mouse that is both durable and relatively lightweight.

Verdict: 4/5

It is not the best in its class, but it comes very close to true brilliance. Great software and lots of great features make this a solid option for a gaming mouse, even at the slightly higher price point.
