Corsair M75 AIR Wireless Ultra-Light FPS Gaming Mouse – 26,000 DPI – Ultra-Fast Input – Symmetric Shape – iCUE Compatible – PC, Mac – White

Really good at a discounted price, but better alternatives
Pros:- Light weight- Standard wireless tech/behavior- Really nice shape for a symmetrical (personal opinion)- Good quality PTFE feet- Nice little storage compartment for the dongle- Optical switchesCons:- No USB-C dongle attachment- Less than perfect build quality- Wake up delayThoughts:I picked this up at about $80 here on amazon. This should be it’s normal price. Any higher, and I would recommend looking at something else. That said, the mouse is pretty good. I really like the shape for a symmetrical. It feels like a combination of Logitech’s superlight and 305. The way it tapers toward the front feels really good to me, almost feels like an ergo which is my preference. It behaves as you would expect a mouse to function, so no knocks or extra praise to performance. The optical switches feel pretty good, maybe a little spongy, but they felt fine to me. I always like the inclusion of optical switches because they tend to be better about not developing double clicking over time.On to the cons. I think it’s strange that this doesn’t include a USB dongle attachment. That thing that you plug the dongle into, then plug your charging cable into to let sit closer to the mouse. I only list that because most other mice include that, and it prevents you from having to either take up 2 USB ports, or constantly swap the dongle for the charging cable. Less than perfect build quality. My copy has an ever so slight creak on the sides. Not very noticeable in gameplay, but I’m aware of it. There’s a slight wobble on left and right click. This last one’s a little bit of a personal gripe, but one I really don’t like on wireless mice, wake up time. After using a Superlight and Pulsar mice, anything slower than an instant wake up feels bad to me. There’s a good 2 or 3 seconds before the mouse wakes up, and it just feels bad. If this doesn’t bother you, then ignore this, but it’s there if you care.Conclusion:The gaming mouse market has very stiff competition. This mouse is alright, especially if you can get it for around $80. Corsair still need to work on the general quality of their mice in my opinion. The keyboards seem fine, but the mice still feel a little cheaper than their competition. Before you buy any mouse, don’t be afraid to look at names outside of the big ones (logitech, corsair, steelseries, etc…). There are so many dedicated gaming mice companies now that offer really high quality mice for the same or sometimes lower prices.

OVERPRICED Absolute Junk DON’T BUY
This is coming from someone who loved Corsair products have used their mouse and keyboards for the past 6 years this mouse is making me switch over to logitech because each “new” mouse Corsair comes out with is WORSE than the prior models.The only good this about this mouse is that its light and has a okay hand feel that is IT!The battery dies insanely quick having to recharge it everyday even though it goes into sleep mode after not being used for 30 minutes. The katar at least could last 3-4 days before it was low on battery. the entire mouse feel cheap if you grip it even a little to much you can hear it creaking and cracking because the whole things is made out of cheap plastic. If you sadly waste your money buying this mouse you are FORCED to use their shitty Icue software which is more akin to a virus than anything useful. it you try to use the mouse without Icue its doesn’t work as intended, the back and forward buttons on the sides CANNOT be used as mouse button 5-4 without you programing them to a key on your keyboard. meaning you lose the ability to use the back and forth button while on youtube ect. After you reprogram the side buttons to you can use them in a game you have to keep icue open or it reverts back to not being able to be use. MOST IMPORTANTLY get used to your mouse disconnecting randomly and reconnecting after a few seconds. this mouse REPEATIALY disconnects despite the fact it was fully charged and up to date on the bios.If you waste your money on this mouse get ready to have a mouse that feels like crap, doesn’t always work, and when it does it barely works correctly. if i could give it 0/5 i would

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 wellCons:+ 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 issuesIn 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!
