Corsair M75 AIR Wireless Ultra Lightweight Gaming Mouse – 2.4GHz & Bluetooth – 26,000 DPI – Up to 100hrs Battery – iCUE Compatible – Black

No es el mouse mas ligero del mercado ni mucho menos, pero es un muy buen Mouse

I recently picked up this mouse and it has been a great addition to my setup. The first thing I noticed was how lightweight it is. Moving it around almost feels effortless, like it’s gliding across the desk, which makes a big difference during longer gaming sessions. The buttons have a nice, crisp sound and feel to them. Each click is clean and responsive without feeling too stiff or too soft, which gives a good level of confidence while using it. Performance-wise, it’s been excellent for gaming. The response time feels very low and consistent, and I have not experienced any lag or delay. It keeps up well in fast paced situations and feels reliable the entire time. The battery life has also been impressive. I can get through the whole week without needing to charge it, even with several hours of use during the week and 6 or more hours of gaming on the weekends. Overall, I am very happy with this mouse. It performs well, feels great to use, and holds up nicely over long periods of time.

This mouse surprised me with how lightweight it was and how intuitive in response. Battery life takes a little hit due to weight but I'm okay with the trade off given how easy it is to work with.

Wireless does not work very well. I’ve been using the mouse as a wired one the entire time I’ve owned it. Even as a wired mouse, it will randomly stop working. As someone who plays a lot of competitive PVP games such as Valorant, this is extremely frustrating. The mouse will disconnect for half a second and then I will lose a fight due to it. The polling can only be upped on wireless but iCue barely ever registers this mouse, even when it’s plugged it. Cannot change polling rate or DPI without iCue. To fix the iCue thing, you have to repair the app. Which gets annoying to do every time I turn my PC on. In terms of battery life, I cannot make a statement because the wireless barely works and constantly disconnects so I have been only using it wired. The mouse feels fine for what it is but it’s overpriced for a mouse whose wireless does not work (so basically a corded one) and has no RGB, no dpi control on the mouse itself, and only has 2 side buttons. I understand lacking these things makes it lighter, and it is air, but this mouse does not feel like what I paid for. This is my second Corsair mouse, my last one being the Dark Core RGB Pro. That mouse lasted me 4 years and I only upgraded because 1 of the side buttons started to stop working and I wanted to try a light mouse vs Dark Core being considered heavy. I’m well versed in Corsair and usually love their products. I’ve been using this mouse for a couple months now and I WANTED so badly to love it as much as I love Dark Core, however I will be getting another mouse.

TL;DR: Great mouse but some connectivity issues and issues with Corsair's software prevent this from being a perfect mouse. For the price, I wouldn't expect to have quite so many issues. Would only recommend purchasing if you can get this mouse on-sale. See bottom of review for my recommendations on how to best use this mouse to avoid issues. The Corsair M75 is a stunning piece of equipment with a few flaws that are forgivable but still worth noting. Pros: + Really light, yet solid construction + Sensor is fantastic, 2000 Hz polling rate does feel smoother + Connectivity over 2.4 Ghz is easy and works well Cons: + Bluetooth connectivity is hit and miss + Major problems using this mouse on a USB Hub/KVM switch + Corsair's iCue Software + (Updated Review) 2.4 Ghz connectivity can have issues In my current PC I have tried to use Corsair for most of my components and peripherals in order to minimize the number of apps running on my machine. So when it came time to replace my old mouse that had developed double-clicking issues, the M75 seemed like a great option. Right away, I noticed the mouse feels amazing. It's really light - and I know mouse critics say its "not the lightest mouse out there" but seriously it does feel like pushing around a couple of cotton balls - it's really light. The shape feels great. I have a medium-sized hand and I play games with a claw grip and this mouse feels fantastic. In fact, after three hours of gameplay I had nearly zero wrist or arm fatigue. The construction is solid. I've watched critic reviews that mention a bit of wobble in the mouse wheel, but on my M75 I haven't been able to replicate that. Overall for such a light mouse, the frame feels incredibly strong and there are no wobbly parts that I can tell. The only minor downside is that the side buttons are fairly flush with the side of the mouse, which I didn't think would be much of an issue, but I can see that it doesn't feel quite as natural as when the side buttons are raised. The sensor is excellent. When using 2.4 Ghz, you can run the mouse at a 2000 Hz polling rate which did give a noticeable change in the smoothness of the cursor movement on screen. This smoothness made the cursor feel slightly slower, which I was able to compensate for by increasing the DPI. Desk surface calibration worked well although I didn't notice any difference before any after. The wireless connection at 2.4 Ghz works well and connects seamlessly, which unfortunately I can't say about the Bluetooth connectivity (more to come). I like that I can run the mouse at 2000 Hz polling rate over wireless compared to other mice that require the wired connection to go above 1000 Hz. There were a few downsides to this mouse that I noticed. First, using the mouse on Bluetooth is painful at best. I have two computers (work and gaming) and aimed to use the Bluetooth connection with my work Macbook Pro. While I was able to pair the Bluetooth after looking up instructions online (no manual is included with the mouse), after switching back to 2.4 Ghz for a gaming session, I have been unable to get the mouse to reconnect to anything via Bluetooth since then. As a result, I fear that I will need to continue having two mice on my desktop - one for work and one for play. The next problem that I noticed, was that when I connected my 2.4 Ghz receiver to a KVM switch/USB hub, it caused my gaming PC's processor to go nuts during gameplay pinning the CPU at 100% utilization and dropping framerates below 30 FPS in League of Legends (I usually sit around 244 FPS on that game). I was able to solve this issue by plugging the wireless receiver directly into the back of my PC - but if you plan to use a KVM switch, you might want to look elsewhere. (Update) Having now used this mouse for several months (exclusively for gaming), I can say that this mouse' biggest issue is overall connectivity. The most common issue I've seen is that the mouse input will stutter, slowing down for perhaps half a second which can be deadly in fast-paced games. This will happen probably 2-3 times in a three hour gaming session. A less frequent issue that also occurs perhaps once every two days are instances where mouse clicks don't register properly. This rarely happens, but it is noticeable and at this price point I would expect zero missed clicks. The third and final 2.4 GHz connectivity issue that I've experienced only twice is when the mouse will completely stop sending input to the PC, requiring me to remove and re-insert the 2.4Ghz dongle. Lastly, Corsair's iCue software which is fantastic in principle, definitely has some issues still. I was unable to update the mouse firmware on my Windows 11 PC (using a cable connection) and had more success updating it on my Macbook Pro - although I did receive an error that the update failed, my mouse now shows that it is using the most recent firmware. What I've also noticed is that as more components are added to Corsair iCue, the software gets more and more buggy. The mouse and the receiver are listed as two separate components in iCue, and along with my other half-dozen peripherals and parts, iCue seems to be struggling to run properly - often crashing on Windows startup, or displaying errors. Keep this in mind, if you use iCue with some peripherals or parts already in there, you'll likely see a reduction in app stability as you add two additional components (the mouse and the wireless receiver). ----RECOMMENDATIONS TO GET THE MOST FROM THIS MOUSE---- While there's not much that can be done about Corsair's software or the spotty multi-device connection, I did find that my issues with the 2.4GHz connectivity were resolved by moving the 2.4 GHz receiver onto my desk rather than leaving it plugged in to the back or front/top of my PC. It seems that shortening the distance between the mouse and the receiver to less than 1.5 ft. stops the dropped mouse clicks and stuttering mouse movements. A good USB extension cable or a mouse pad with a built-in USB port is a great way to achieve this. If you have trouble updating the firmware, try updating it on another device. For some reason, I couldn't get my mouse firmware to update on my main gaming PC but it did work on my Macbook Air. ----OVERALL---- All in all, I would definitely recommend this mouse for a gamer who plans to use this mouse exclusively on their gaming PC without a KVM switch or USB hub. It feels great and is super snappy. If you're looking for a double-purpose mouse to run across multiple machines, I'd recommend looking elsewhere. Happy gaming!
