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.

Solid weight, but mouse wheel feels a bit too clunky. Issues when using for games needing the option.

Amazing feel and feed back and is an amazing addition to the set up

Works great! Feels great in the hand and does everything it should!

Awesome mouse, fits my hand perfectly and gets the job done. GG

This mouse works great but the price is pretty pricey.

Its easy to adjust the sensitivity, i can use it casually for work, and then with the click of a button, i can ramp up the sensitivity for my gaming.

The mouse is amazing and the software is amazing too. It also has a great shade of orange compared to others.

This Gaming Mouse was a perfect fit for my son He loved it because it fit his hand better than other mouses and was compatible with his PC and his Playstation.

This is a great mouse also, just and amazing like ny new alienware, and also a great price and functions, Im a graphic designer and I LOVE IT

It was a perfect mouse with no issues until 8 months later when the clicker broke.

Great mouse. I normally opt for wireless but that was giving me issues as of late. 10/10 mouse

Nice product it’s easy to install and the delivery was fast

Always loved the M65. This new one feels lighter though.

A little on the lite side but work good maybe even mad me a better player

Awesome mouse. A ton of features and the lighting is perfect. Would definitely recommend.

I wanted to give this mouse a try and the more I tried using it the more I regretted it. There's 2 dealbreakers that essentially make it unusable for me, so let's get into that - First is the fact that the mouse is just unstable and rocks side to side either because of the feet or the ledges on the side of the mouse. Next is the software (iCUE) which for me doesn't even want to install despite having enough disk space for it. I don't recommend this mouse alongside many other Corsair mice as they have fallen behind.

This gaming mouse combines a high quality feel with lightning fast response, incredible precision and outstanding customization options. Corsair has clearly put a lot of thought and care into this product, and if you're looking for a great gaming mouse that also works well for desktop use and offers a subtle and understated design, this is an excellent choice that offers a ton of value. Pros: - Great looking design and high quality construction that isn't over styled and will look at home on almost any desktop. - High quality RGB lighting can be linked to other RBG devices, themes, and rules via Corsair's iCUE software suite. - Well placed, top quality buttons and scroll wheel. - Supports re-mappable tilt gestures - On-the-fly sensitivity adjustment with visual feedback. - Adjustable weight - Also outstanding for regular desktop use - High quality, ultra soft cable doesn't hinder movement and should hold up well to heavy use. - Easily switch between multiple profiles Cons: - The multiple profiles cannot be activated just be running a particular game or program. - Sometimes in extended sleep mode, the mouse seems to disconnect and moving it won't wake up the computer. Sometimes you also need to wait moment for the mouse to re-connect after waking up the machine. In practice, this is a minor issue. I've been using this mouse for shooters like Halo Infinite and Battlefield V, and RTS titles like Supreme Commander 2 and the new Age of Empires. In all cases, performance has been flawlessly fast and accurate. It's incredible what a difference a truly well designed mouse makes in being able to achieve smooth and accurate movement and targeting, and the sophisticated remapping options allow you to keep all key commands ready at hand. Additional touches such as gesture controls (just tip right to reload your weapon, for example) and a super low lift-off distance make it that much more enjoyable to use. Corsair's iCue software provides a nice central management interface for adjusting, remapping, and controlling RGB lighting on the mouse. The software can also control other RGB devices, including some not from Corsair (my ASUS motherboard, for example). You can also save some profile data directly to the mouse hardware as a fail safe or to allow customization even when the iCue software is not available. In addition to gaming, I've also found this mouse to be ideal for regular desktop work and found it very difficult to go back to my regular work mouse. I'd go so far as to say that if you use a large high DPI display, this mouse is a great choice for anything from Photoshop to Excel work and if you prefer the RGB effects can be disabled for a work-specific profile. Don't let the wired connection concern you. Not only does it provide ultra-fast, low latency, and reliable input, the cable is very soft and covered in a high quality braid. In practice I didn't even really notice the cable during gameplay. There's an obvious level of care and understanding of the needs of gamers that has gone into this product and I can recommend it without reservation as providing a ton of features in a high value package.

This is the worst mouse ever used..... had a corsair for years upgraded to this trash didnt even last a month. Multiple problems. Honestly dont waste you money.

Mouse is great. Very responsive. Colors are cool. Highly recommend
