Customer Ratings & Reviews

While I don't recommend a wireless mouse for competitive gaming, the response times on this wireless mouse feel like it could be used in competition. Either way, it is a great gaming product. I love the weight of the mouse, and the feel of the aluminum frame.

The Corsair M65 RGB Ultra wireless gaming mouse has been reborn as a more refined and prolific version of itself. In my opinion, this is one of the best mouse designs for both work and play. This is the first gaming mouse I have seen that has both RF and Bluetooth in a single device available at the flip of a switch. I can switch between a laptop for work and my preferred battle station effortlessly. Connectivity is available through the USB dongle using 2.4GHz or you can go Bluetooth with the flip of the switch. There are 3 weights you can install to make it yours. Overall, this is a very nice package with beautiful RGB lighting in the logo and plenty of customization using Corsair's acclaimed iCue software. In order to get the most out of this mouse, you MUST use the iCUE software to make it yours otherwise, you just have a really cool basic mouse. The M65 RGB Ultra Wireless is an excellent mouse for FPS or claw grip users. Everything is just in the right place for me, and it is just a beautiful mouse. The plastic is covered in a soft rubberized coating that is very nice to the touch but is a fingerprint magnet. During play, while on the RF connection, there was no noticeable lag due to combination of Omron optical switches and Axon processing. When on Bluetooth, it wasn't terrible, but I could notice it wasn't as fast. The overall mouse size feels a bit small for the palm grip I use at work, but it's manageable. The anodized aluminum frame gives it the build quality needed without sacrificing weight and bulk. The thumb rest has a nice pattern of triangles that looks great and offers a nice grip. The USB receiver is housed in the "right wing" underneath the mouse which is good to keep things together. Now for the specs: Specs Hyper-fast SLIPSTREAM WIRELESS 26,000 DPI Marksman Optical Sensor 8 programable buttons Omron Optical switches Claw grip Battery life 2.4GHz SLIPSTREAM: Up to 90hrs continuous use BLUETOOTH: Up to 120hrs continuous use Selectable 2000Hz/1000Hz/500Hz/250Hz/125Hz polling rates The M65RGBUW is a great all-around package for me but it isn't perfect. I wish the scroll wheel had L/R tilt buttons and a free scrolling/click mode. If the mouse was slightly elongated, it would fill the palm better to accommodate the more comfortable palm grip for times of work and productivity. I wish the included USB cable was braided but it is still a high-quality cable. I absolutely love the inclusion of the gestures to incorporate tilts. This will take some getting used to, but I mapped it to reloading, throwing 'nades, and macros to type in chat which was pretty cool! Using Bluetooth, you can get up to 120 hours of continuous use (however I have not verified). The RGB is accurate and beautifully syncs with my other iCue compatible gear for a perfect symphony of lights, however, at lower levels there are some dark spots you can see. In all, you will not be disappointed however the price is a bit hit in my opinion.

The Corsair M65 RGB Ultra wireless is great. I love the flexibility of the Bluetooth connection. I've used it on a MacBook Pro, Windows laptop, and an Android tablet. In all scenarios the mouse worked great. Very responsive and comfortable to use.

Received my Corsair M65 RGB Ultra Wireless Tunable FPS Gaming Mouse a week ago and have been testing it out. Inside the package comes the mouse, USB Receiver, USB-C Charging Cable, and 3 weights that can be added to the bottom of the mouse. I added all three weights to the bottom of the mouse before I even plugged the mouse to my system. This process was easy as pie; simply add the weights to the open pockets at the bottom of the mouse and use a coin screw the weights in place. I downloaded and installed the Corsair iCUE Software which allows you to tweak the mouse (and Corsair Gaming Keyboards) to your hearts content. You can change everything from the color schemes to the DPI (which goes up to 26K). The software also allows you to update the firmware for both the USB Receiver and the Mouse itself. The M65 features 8 buttons: 1. Left Click Button 2. Middle Click (Scroll Wheel) Button 3. Right Click Button 4. DPI Up Button 5. DPI Down Button 6. Forward Button 7. Back Button 8. Fire/Sniper Button Using the mouse for me was very easy. It felt great in my hand, however, the one issue I seemed to kept having was my thumb always wanting to hit the fire button on the side of the mouse. Which I wouldn't necessarily say its a design flaw as I have fairly large hands. One feature that I love about this mouse is that Corsair gives you the option to connect the mouse via wireless or Bluetooth. Overall I would say Corsair hit this one out the ballpark and they continue to amaze me with the different products (mice, keyboards, headsets, etc.) they continue excelling at for PC gamers.

Pro: -Great solid construction -Weight tunable -Bluetooth and wireless -Tilt gestures Con: -Shorter grip -Clicks are a bit soft This mouse is well built and has a good heavy heft to it, even without the added weights. The aluminum build feels solid and doesn’t have any creaking or hollowness to it at all. I prefer heavier mice for most of the games and even work, so I really liked how this mouse feels. However, for my palm grip, it’s too short to grip on comfortably. The mouse is about an inch shorter than my other gaming mice. I have slender hands and even so, most of my palm is not touching the mouse and it’s slowly shifting further back. I see this being more suited for a claw grip. The clicks are responsive, but also feels lighter and softer. The sniper button could maybe be a bit further back, but these are nitpicks. It has tilt gestures that you can assign actions to which can be useful, but I didn’t use them. The battery life seems good. I used it for a while and never had to charge it. The slipstream receiver can link other slipstream devices together but the range is short and needs direct line of sight. I have my tower right next to my monitor and plugging it in the back would cause dropouts. The mouse can either be used with the receiver or bluetooth with a flick of the switch. The iCue software lets you do surface calibration, tilt gestures, and of course the RGB. I’ve used iCue for a long time and I don’t have any negatives to say about it. The UI can be better, but overall it works fine. I’m somewhat ambivalent about this mouse. I like the build and the heavier weight, but the shorter design is clearly made for a claw grip. While a palm grip can still use it, it wasn’t that comfortable for me. It’s still a good mouse if it fits your grip.

I had a Death Adder Elite back some years ago that I absolutely loved! It was very quick moving & allowed me to effortlessly move about in Counter-Strike: Source (yes, I still plan it now too?). I remember playing for hours on end and just loving that mouse. I changed it out for a Corsair noise since I was going with all Corsair equipment peripherals. Sadly that Corsair was a bit heavier & it threw me off at first but I mead able to make due. I was back to my old high scoring self in CS:S in no time! But I still wanted to try to find my holy grail: a Corsair mouse that had adjustable weights, felt light as a feather & was able to integrate with my other peripherals. I was over the moon when I saw this mouse! It is precisely what I had been looming for! Installation was a breeze, but I do have a love-hate relationship with iCUE. The software sometimes has a mind of its own and this go around was still somewhat the same of losing my configs, not saving the configs, etc. All in all thought I am happy. I played a while in Apex Legends, CoD, CS:S, CS:GO, Rainbow Six Siege, and many more. I can tell you that for me both wired & wireless the mouse performed the same & it was truly amazing to use. I fell back in love with a mouse again! Lol I have let my kids play with this & my other Corsair mice. They too really dig this Corsair M65 RGB mouse. And one of my sons even mentioned the DAE & how it was similar according to “some YouTube gamer”…yep, it is son…it definitely is! And I couldn’t be happier. Lastly, whether using Bluetooth to my phone, wireless on my laptop or wired on my gaming desktop the Corsair M65 does not disappoint. Still unsure? I’ll be getting more so I’ll be sure to thank you for leaving one for me because I want extras on hand so when kid breaks it (rage quitting teenage gamers are a thing ya know), I won’t miss a beat and can continue on with my glorious Corsair M65!

The Corsair M65 is the best mouse I have ever used. I don't think such a thing as the "perfect" mouse exists, but this is close. Ergonomics are a personal thing particularly with gaming mice. But the M65 falls into my hand like it was meant to be there. Very comfortable and the buttons are placed perfectly. I also love the adjustable weights for fine turning the "feel" to your liking. Also, the battery life has been awesome so far. Using the iCue software is a must. It allows for a lot of customization. RGB lighting on a mouse isn't really a big deal to me. But you can really customize the lighting a lot. Also (and more importantly) is the ability to fine tune the DPI. Using the M65 for everyday computing works great as well. I've been using it for both gaming & general use and have had no issues in use or comfort. But realistically, general web browsing isn't something you would really buy this for. All in all, I couldn't be happier and I can highly recommend it.

This mouse has been another great product from Corsair. Every button and switch has a positive feeling without being loud or super clicky. It feels rock solid with the aluminum frame. I could detect no flex or anything in the frame whatsoever. Settings are adjusted through the iCue software like any other Corsair product, so it is easy to use. While I found this mouse to be comfortable in general and a joy to use, I couldn't help but notice my average-size hand felt too big to get a solid grip sometimes. It all comes down to personal preference, but I prefer a slightly wider mouse, especially in the back half, to get a solid grip. I would recommend this mouse for small to medium hands, but anyone with larger hands will probably not find this mouse particularly comfortable. Subjective comfort aside, the performance, build quality, and features of this mouse are excellent for the price.

The Corsair M65 is one of the best wireless gaming mice I've used! The customizable weight is great and allows you to dial in your perfect settings. The feature I was most skeptical about was the "sniper" button but, it's great! All of the buttons are fully mappable in iCUE, subtle RGB lighting, and very sturdy construction. From the top, the mouse is very subtle and will blend into most environments, from any other angle it is clearly for gamers and power users with its exposed aluminum frame and big red "sniper button," ready to be mapped to do whatever you'd like it to do! I highly recommend this for anyone who is really into fine tuning their mouse to fit their needs and likes a heavier device.

The mouse feels good and tracks extremely well. The weight adjustment is a nice bonus and I almost forget I have a mouse in my hand. Customizing the lighting to my keyboard and PC lights was easy and the battery life is super. I really like this mouse.

Great mouse fits my hand like a glove. would recommend to any one looking for a mouse.

Not sure how so many people rated this mouse highly. I was coming from the corsair dark core pro and wanted to try this mouse out. The latency is horribly slow and the actuation for the left click was way heavier than I was expecting. There are definitely a lot better mouses on the market.

The mouse was okay. Was glitching a lot and skipping. Says it needs an update even after I update it. Tried to get a replacement but was told my warranty expired the day before.

I recently changed from Logitech to Corsair, this was among the first items I picked up when I did. In no way am I disappointed.

i got it when it was on sale i like this product. i recommend this item

High quality product, Plethora of configurations and colors.

Works amazingly best mouse ive bought yet. Love it

Hands down the best gaming mouse I ever had the pleasure of using.

Very nice to use until it broke. I most likely buying another but be warned the left click button stopped working after about a month.

not even 3 three weeks old the middle mouse button stopped working entirely, all of the other mouse buttons feel incredibly dull and it is an uncomfortable fit. The sniper button is much more a problem than useful.
