I love the feel of the side grips of this mouse on the hand. It's a great design for the gamer in mind with soft rubber side grips making holding the mouse a breeze. The optical signal is extremely powerful for mouse pointer acceleration and feedback on just about any surface imaginable. The side buttons are perfectly positioned for effortless side-click for buttons 3 and 4. The Mouse wheel is solid and has great scrolling functionality along with a push-action feature doubling as another mouse button. The top buttons take some getting use to and are slightly more difficult to activate with one finger however the further button options are nice. The mouse comes with built in pointer-acceleration speed buttons on the side to choose your preference on the fly. I found the wireless mouse signal to be adequate and with little lag if the battery is fully charged. The battery in wireless mode has a good lifetime before needing recharge.

This is my second Corsair Elite RGB mouse. I blamed regular wear and tear on the loss of left click functionality of the first mouse after a year of use. I had hoped if perhaps I was gentler this would be avoided the second time and after just 3 months of use this left click issue has surfaced again from regular to soft click useage. After taking it apart it seems the tiny metal conductor under the tiny blue input button folds in or was squashed and will stop functioning entirely from just regular use. This is a manufacturer's fault in design as the mouse is supposed to be clicked over long periods of time. It's an expensive mouse and will be my last.

As you can see it has great design strengths overall however the near guaranteed degradation of the left mouse spring inside the housing means you will be buying a replacement within 3 months to a year.

For the average person the mouse is a good size and weight. For various sized hands you can slide the 12 side button up and down the mouse which made placing my thumb on them for quick access that much easier. I'm a video editor, photographer, photo editor and gamer of all genres. So the extra buttons come in so handy I can't sing it's praises enough I will be alone in this but I use the side buttons for First Person Shooters as well as MMO's, MOBA's and even RTS games and again LOVE using it! As stated in the weaknesses the scroll week doesn't work anymore, the middle click still works though. I'm listing this as a strength as I've had 4 razor mice in the same time that I've had this corsair mouse. 3 Razor naga's and a death ader and all of them kicked the bucket in a much shorter time. I may have had some bad luck but that just my experience with other mice.

The 12 side button are a little hard to get used to as they are so flush with each other its hard to distinguish between the buttons based on feel alone. After many years of use the scroll wheel no longer works. Although disappointing, don't let this be a deterrent as I've used this mouse for so many years I can't remember at this point.

And excellent mouse all around for gaming of all genres, productivity work such as video editing, photo editing or even 3D as 3D software has A LOT of hotkeys to memorize. Build quality is good and I don't have complaints about it other than the weaknesses stated in this review. If you think you'll have a good use for all these buttons, but all means get this mouse. It's also a great value in comparison to the other mice you can get with the same features and build quality. I think this is the sweet spot for price to performance.

It is a well sized mouse, and the adjustable positions for the thumb pad is great.

Probably the worst software I have ever dealt with from a gaming peripheral. The customer support is also some of the worst I have experienced. I have to constantly unplug and plug it back in. In order to get my onboard profile to work properly I have to turn of the iCue software. Not as user friendly as the Razer Naga, or Logitech G600.

The mouse works well as long as you can deal with the very glitchy and hard to navigate profiles/software. I will not buy this again, nor can I recommend anyone buy it until they do something better with iCue.
