Gaming mice are often suitable for a certain type of PC gamer, namely someone who is right-handed. If you’re left-handed, the options field looks decidedly disappointing. The Corsair M75 Wireless addresses that somewhat by being a true ambidextrous gaming mouse, allowing you to easily switch between the standard right-handed mode and a left-handed setup.
At least that’s the idea, but in practice it’s not as simple as just pressing a button. The first thing you need to do is remove the magnetically attached side buttons on the left and the blank covers on the right and replace them with inverted buttons that come in the box.
I’m certainly not hammered in any way, but oh boy, it’s a tricky process. Once that’s done, all you need to do is head into the iCUE application, click on the settings gear icon for the M75 Wireless, and then select Left mode. And there you have it: a universal gaming mouse.
But is it one? Good universal gaming mouse? I mean, being completely right-left is all well and good, but if it fails at being a decent mouse in the first place, then it’s all for naught. Fortunately, there is the Corsair M75 Wireless is a good gaming mouse. It’s not great, mind you, but it’s not so far off that the next revision of it could be perfect.

Hardware-wise, there’s nothing special about it, but what’s there is fine: five buttons in total, sporting ‘zero gap’ optical switches under the main mouse buttons, a decent optical sensor and a low-latency 2.4GHz wireless dongle. Oh, and RGB lighting under the logo and in the bottom of the mouse. These are all pretty much standard fare for a $100+ gaming mouse, but they all work fine.
What doesn’t work quite well is a subjective matter. The M75 Wireless, for example, weighs 89 grams, which is not very heavy, but not particularly light either. Corsair makes an RGB-less version of the M75 Wireless (the M75 Air Wireless), which is a whopping 20 grams lighter and also cheaper.
Compared to some mice I’ve tested lately, the M75 feels a bit cumbersome, and in part I think this has to do with the mass distribution within the chassis.
Of course, all wireless mice require a rechargeable battery and the one in this Corsair model lasts 105 hours via the 2.4 GHz Slipstream wireless connection and with RGB lighting turned off.
This increases to 210 hours via a Bluetooth connection, but you don’t want fast gaming on that system. Regardless, that’s a pretty decent battery life and Corsair’s numbers seem accurate from the time I used the M75 Wireless.
I suspect the mouse contains quite a large battery and it feels like it is positioned a little too far towards the front of the mouse, rather than being positioned more towards the natural pivot point (i.e. your wrist). Together with the somewhat narrow PTFE feet on the base, the M75 Wireless doesn’t glide around as effortlessly as, say, a Razer DeathAdder V3 Pro.
The side buttons and wheel aren’t perfect either. The former are unobtrusive and during a hectic round my thumb didn’t always push them in properly, causing the game to fail to register the button click.
The steering wheel is a solid affair, but there’s a little more resistance to movement than I’d like, especially in a gaming mouse. In general use it’s adequate, but compared to Logitech’s brilliant MagSpeed wheel system it feels stiff and sluggish.
If you’re a fan of RGB lighting, you might be happy to see that the M75 Wireless is packed with that: the top logo and side strips, as well as the rear edge of the base, can be adjusted independently, with the usual color gamut and timing patterns offered by Corsair’s iCUE app.
It’s a rather subtle affair, even at full brightness, though I do wonder what the point is of a logo that lights up when covered by your hand during use.
And speaking of usage, Corsair’s Slipstream wireless system boasts a 2,000 Hz polling rate – that’s more than what most gamers would ever really need, but it’s also somewhat questionable considering the USB port in which the dongle resides is only polled at the default rate of 1,000 Hz. .
1,000 Hz — The closer the points are together, the more consistently a mouse reports movement. More variation or stray dots make for a less accurate sensor.
1,000 Hz — Each dot represents an update, which corresponds to the polling rate. Every 1 ms should mark a single update on a 1000 Hz mouse.
Here is the same update time chart for a Razer DeathAdder Viper V3 Pro. There are much fewer update spikes compared to the Corsair M75 Wireless.

Using Mouse Tester to examine the performance of the optical sensor and wireless signaling system, it turns out that while the M75 Wireless tracks very accurately, the connection isn’t as flawless as Razer’s HyperSpeed technology.
The second graph above shows several examples with very long update times (well in excess of the 10 milliseconds that would be required). Compared to a DeathAdder Viper V3 Pro I tested on the same PC, it’s clear that Corsair’s Slipstream system isn’t as good as Razer’s HyperSpeed.
I tested the dongle in several USB ports, but the test results were about the same in all USB ports: the peaks were still there, only in some cases they were no longer than 30 milliseconds, but sometimes well above 150 milliseconds.
Buy as…
✅ You are left-handed: Gaming mice for lefties are rare, so kudos to Corsair for making it truly ambidextrous.
✅ You prefer subtle RGB: Even at full brightness, the LEDs in the base and logo won’t turn your gaming room into a disco.
Don’t buy if…
❌ You want a lightweight mouse: While 89 grams isn’t super heavy, the RGB-less Air version of the M75 Wireless is cheaper and much lighter at just 60 grams.
❌ You need a fast and snappy wheel: The overall action is solid, but the initial resistance to rotation makes it a bit slow to use in hectic games.
In most games the spikes in update times weren’t noticeable at all, but there were a few instances in Counter Strike 2 where the screen and mouse weren’t quite in sync. However, it is difficult to say whether this was due to the mouse.
Corsair isn’t marketing the M75 Wireless as a ‘pro gamer’ model, so the standard polling rate will be fine for most gamers, but if you want something that’s ultra-fast all the time then you’ll be better off looking into a other wireless gaming mouse.
With an MSRP of $130/£130/€130, the Corsair M75 Wireless is definitely not a budget-oriented gaming mouse and there’s a lot of competition in this price segment, even within Corsair’s own range. The best wireless gaming mouse you can buy right now, Razer’s DeathAdder V3 Pro, is about $30 more expensive and is only for right-handers, but it’s lighter, faster, and much more fun to game with.
I would be reluctant to hand over the full amount for something that isn’t perfect for me. But right now, Corsair’s offer in the US is just $90, and at that price it’s a really good deal. This isn’t a bad gaming mouse, it really is one Good mouse, but small issues tend to rub off over time.
But if it lost a bit of weight, had a nicer handlebar, and came with larger profile side buttons, I would definitely consider it a great option for any PC gamer. Even if you use the wrong hand to operate it. Sorry, lefties.
