Customer Ratings & Reviews

I just switched over to m&K and I love this mouse I got the matching Corsair keyboard and the RGB configuration is amazing you can switch dpis instantly with the buttons by the scroll wheel and it feels great in hand

The feel of this mouse is excellent. I love the option to change the weight of the mouse. The display in Best Buy sold me on this, but they didn’t have one in stock so I had to order it. The buttons on this mouse feel amazing. In my opinion, this is probably the best mouse I’ve used. I would definitely recommend this mouse to anyone looking for amazing product.

Solid mouse, comfortable due to ergonomic design. As well as an awesome adjustable weight setup.

Level up your game using this pro mouse… I play COD and Age of empires, I can feel the difference between my old normal mouse and this pro gamer mouse with a lot of extra buttons .. great quality and comfort… the weights can be add or remove as convenient.

After my previous MX Master 3s died and i needed a new mouse Corsair came in clutch again. I at first tried the razer basilisk v3 and it was great hardware wise but the software just wouldn't work for me at all. So after returning that mouse and getting this one its fantastic. I had the old version of this mouse in the past so I'm very familiar with it. The sniper button is great to use in fps games. It might be a bit small if you have bigger hands. Ergonomics are great. The performance is amazing. 26k dpi is insanity. Most importantly it is very VERY reliable. I've had no issues with software or anything else. The wire might be a bit annoying but it gives next to no latency delays. I would definitely recommend this. But if you really want s great deal get it at a discount.

Perfect size. super responsive. Rgbs look great. Easy to use ICUE

I never realized I wanted weights for my mouse, but now it makes using others feel wrong! I like the feeling, more substantial than a unweighted. Satisfying! Setup with iCue app and customized the colors to match with my K70 Core keyboard.

Good mouse. I needed something with extra buttons on the thumbs and this even has a curser slow button. Good for fps games.

Great addition to my gaming build. Smooth wheel movement, weights help the “feel”. And as an rgb fan, like that it works with my other Corsair iCue stuff.

This is the perfect mouse for fps games with the built in sniper button it’s made for hitting the perfect shots. The simple plug and play with the attached cord makes for easy setup and ease of use. The side buttons and adjustable DPI buttons allow for quick access to important controls too.

I have used this brand and almost every style they have came out with and I just get more impressed with how many studded changes can greatly impact the overall design of the mouse 10/10

I had the previous model of this mouse and loved it. So after many years of use, when it finally kicked it, I had no intentions of getting a different one and purchased this one. It's no different and I love it all the same. 10/10, will buy again in a few years

I came from the M65 elite and so far this feels as close as possible. I’m hoping the optical triggers for the mouse buttons will alleviate some issues I had with clicks not registering on the M65. One surprise feature I didn’t know about is this mouse has a gyroscope. You can now bind actions to tilting the mouse in different directions. This has been a really neat feature for productivity features like copy and paste.

The mouse works great. Its smooth and light so faster reaction time in games. It took me 3 days to accustom to it from my 15 button mouse I had and I found this mouse is a better fit. 15 buttons on a mouse is just stupid over board especially since it s difficult to reach all the buttons on the side of the mouse.

Excellent mouse, fits in the hand just right , smooth and very configurable. Highly recommend!

Love this mouse you wanna beam some people this is it!!! Love how heavy it is

Awesome mouse like the texture better co. Pared with my previous mouse the regular m65 RGB Elite which was kind of smooth. Definitely an upgrade.

Reliable, consistent and everything you want in a mouse. I only use the m series and Corsair mouse products for a reason. My first one lasted 5 years and this one may outlast the first one now I am more caring for my belongings. Highly recommended. 9.5/10 only bad part is the wire can come bent and it is hard to unbend.

I really didn’t like the mouse overall, because the texture was too smooth for my hand. I much prefer the more aggressive texture of the Razer Basilisk. I also didn’t like using the bloated iCUE software. But one thing I did like is that I could configure the RGB lighting once and save it to the mouse’s internal memory. Unlike my Razer mouse, this meant that the Corsair mouse could remember my LED settings without the software running in the background.

_____ *Pros: -Cool-looking design. -Very light with 3 adjustable weights included. -Clickity, responsive, & reliable buttons. -The left, right, and middle buttons are quiet when pressed. -Scroll wheel has right-on resistance and it's easy to modulate. -Ergonomic and comfortable. -Fantastic dpi range, up to 26,000 and 8,000 Hz polling rate. -Affordable and reasonably priced. -Many adjustable settings via the iCUE app. _____ *Neutral: -The Corsair iCUE app is a big download and clunky to use. -The iCUE app's menus and fonts are too small and waste a lot of screen real estate. _____ *Cons: -The iCUE app's tutorial prompts suck and aren't very helpful. Like many people who love PC tech, I love and enjoy Corsair products in general and the M65 RGB Ultra wired mouse did not disappoint. Hardware-wise, the M65 Ultra checks off everything I want and need from a gaming mouse: cool and slick-looking design with an ergonomic and comfortable in-hand fit, excellent build materials and quality, responsive and accurate switches and sensors, and a companion app that lets me customize LED lighting and set up custom button macros. Just as Corsair impressed me with their high-quality and reliable AIO watercooler systems and power supply units, the M65 Ultra gaming mouse has created another positive impression of the company and their PC offerings. I own several other gaming mice, such as the Logitech G Pro X Superlight, Logitech G903 Hero, Logitech G703, and the Razer Orochi V2. Compared to them, this $69.99 M65 Ultra from Corsair offers higher performance for the money spent and represents very good value. If I knew how good the M65 Ultra was beforehand, then I would've skipped out on several prior gaming mice purchases. Most of my other gaming mice are of the wireless kind and I specifically chose a wired version this time because ever since I started gaming on my 55" TV, I noticed severe and undesirable input lag from the wireless mice that negatively affected my enjoyment of fast-paced FPS games. Simply put, the wireless mice introduced too much input lag and made me strongly dislike playing games on the TV. This M65 Ultra, being a wired mouse, eliminated that annoying lag, and my gaming experience on the TV is just as enjoyable as playing on my 27" PC monitor. Although I'm super satisfied with the hardware, I'm not so keen on the Corsair iCUE software. It's a big, bloated, and unintuitive app weighing in at over 800MB. Also, the app is clunky and the tutorials are not very helpful. For instance, after I made all of my LED and macro customizations, I got a prompt notifying me to save my profile inside Device Settings but when I clicked on Device Settings, there was no simple menu option there to save my profile! To keep my customizations, I had to navigate to the Dashboard tab, click on the icon that represents "Customize Dashboard", left-click to toggle on or turn on the "assigned actions", then click the Apply button. Saving a user profile shouldn't feel like rocket science and Corsair needs to make the app more user-friendly. When it comes to software, Logitech does a MUCH better job, IMHO, and Corsair really should revamp the iCUE app to make it more user-friendly. Another aspect I disliked about the iCUE app is the amount of wasted screen real estate. The fonts are so small and the menus are unnecessarily complicated. Despite all the negativity I'm directing toward the iCUE app, my overall impression of the M65 Ultra is still positive because the hardware is good and one can choose to skip using the iCUE app if you so desire. Yes, you'll miss out on some features such as custom macros and dpi switch settings as well as LED lighting effects, but it's still possible to use and enjoy the mouse as-is out of the box. Since the M65 Ultra should be judged for both its hardware and software facets, I rate it 4 solid stars out of 5. If Corsair improves on the iCUE app, then my rating will be higher. === Is it a good buy? === Yes. For $69.99 (as of 2022-01-14), you're getting a high-quality and premium build quality mouse with excellent sensors, response rate, and a good deal of customization via the iCUE app. Just be aware that the iCUE app isn't that intuitive and simple to use.
