Customer Ratings & Reviews

Optical Switches version so far is holding up well by not having double click issue. The RGB lighting is customiable in the iCUE software. When you have your DPI settings set you can save them tot he internal memory for the mosue and close out ICUE software so it isn't running the in the background. The weight of the mouse feels perfect. You can choose not to install them or have only 1 or 2 installed.

I stream on Twitch and play a lot of video games, so far, after a month of playing, I am very satisfied with this mouse. The cord is Soft and not rigged, making it hard to notice it's plugged in at all. All the buttons click and are very responsive, the mouse wheel works! It doesn't have a smooth action, but it hasn't broken yet. adjustable speed and a sniper button that will lower your mouse speed for precision shots!

Comfortable and easy to use, and a couole of extra buttons to work with on the side, without being overwhelmed by 9 extra inputs like other gaming mice. Adjustable weights and sensitivity make it easier to adjust for faster reaction times while maintaining control on games. The size fits well in my hand unlike my previous mouse which I kept losing my grip on because of how smooth and small it was.

Quality of corsair products has been hit or miss these past few years but this mouse is an absolute beast. I love the way it feels, and the options in icue are fun to tweak

Works as intended is comfortable and glides easily. The weights sre an adddd bonus

You can map out the buttons, change the color of the lights. Has a braided cord and is very responsive.

This mouse checked all the boxes I was looking for. I did not add any weights, as I am primarily using it for gaming. It has the amount of buttons I was looking for, and being able to reassign all buttons through their app made it all come together. It tracks very well, all the clicky clicky buttons are as expected and perform well, my only (minor) gripe would be the Ergo doesn't fit my hand quite like other more familiar mice do.

Very smooth & the weight’s make the mouse feel better

My all time favorite mouse been using these for 6 7 years. The sniper button is very useful for certain games and is impossible to use other mice after using this. I’ve bought multiple and store them Incase this product stops being made.

Perfect mouse for somebody with a claw grip. Doesn't have that huge mound that your hand has to sit on. Very wide and comfortable. Grippy. Very natural feeling contours for the hand. Can be as light or heavy as you want. Mouse clicks are on the quieter side. Snappy. Decent software support. The software can be a little convoluted to reprogram key functions, and there are a lot more programmable features than a casual user might be comfortable with. Great fit, finish, and feel. Buy one.

Settings are easy to use fun to use and changing colors is easy

Can't complain, works well. The mouse buttons are a little too easy to click for me but i'm getting used to it

Feels great on both smooth and hard surfaces, plus some adjustment for weight if you like that kind of thing. Rgb looks good but you have to use their software to make it look any good and its fiddly

biggest selling point of this mouse is the larger grip surface area which is great for my larger hands. Helps to dispel cramping after long periods of use. The weights add to the heft of the mouse which is alot more stable to me as well. the DPI is expansive and the mouse has just enough buttons to accommodate my gameplay without being overkill

Overall this is a great mouse, my only issue is that I can not bind the "the sniper" button on the side of the mouse to do anything. User error probably, but I have gone through several reddit feeds to bind the button and have had no success. That is a minor issue that really does not effect using the mouse for gaming/office work.

Excellent Mouse. Lightweight, but has enough heft for feedback due to included weights. Icue software is nice to control everything and build quality is supreme.

Mouse is very comfortable in the palm. It has a good weight and moves easily across surfaces. Tye sensirs are high quality and haven't given any sort of inaccuracy or jittering issues. Would recommend.

This is exactly what was needed. An awesome upgrade to what we had. Great value!

Such a amazing Wired Gaming mouse for the price. 26k DPI, weighted for 40$ is a steal, especially with the Total+ discount. Thank you best buy.

Time will show if left click issue gone from m65 series as claimed by corsair. So far 5 stars, icue software is a little confusing but got it working after a little search and consistent retries trying to get the profile to save to the mouse. Now that it's saved, uninstalled icue and wont use again unless need be. I'm a legacy user for the m65, started with the Vengenace m60, had three, broke from user abuse. Stayed away from left click issue ridden m65 series, until now. M65 Ultra claims to have the omron click switch that the m60 had, and said to be an update from the m65 elite, save for a million clicks before wearing thin. Will see in time if the ultra really has fixed that issue. You can be sure to follow this post because i will update if an issue arises and in a year or two or if the mouse is still left/right clicking okay.
