Summary: If you are ok with a mouse that has a lifespan of 2 years before it starts to go wrong, then it is fine. But if you expect longevity, this mouse was lacking.
Pros: Solid weight, good response, relatively easy access to multiple thumb buttons.
Cons: At the 2 year mark the mouse wheel doesn't respond correctly. Specifically, when you scroll in one direction it will respond correctly initially and then move extremely in the opposite direction. IE if you try to scroll down it will then scroll up violently, or if you are trying to zoom in one di...
Summary: It's a really comfortable mouse and the buttons work great all the time. Good speed, nice movement, everything great, until a few months ago - almost exactly a year since I started using it - THE SCROLL WHEEL DIED. It started jumping down when I scrolled up. 3 or 4 steps up, 1 down.
Summary: This will be that last tie i use corsair if this becomes a pain to get replaced.
Pros: Very well built mouse. love the design and looks pretty cool.
Cons: The wheel started messing up the last few days and now is totally useless. Very disappointed with my purchase. only took one egg off since every other part is working fine. although the wheel really hurts web browsing a lot and some of my games.
Summary: This mouse did end up failing after two years due to a faulty scroll wheel, but Corsair replaced it, no questions asked, out of warranty with the M95 mouse. Corsair takes care of its customers, and I feel a lot better using a product they stand behind.
Cons: Mouse shorts out. constantly. I actually feel a light spark about 30% of the time I first use it. It sparks, then windows loses it's mouse and it takes about 40 seconds to reestablish itself. Single worst tech purchase that wasn't 100% DOA on purchase.
Summary: I'm writing this review after two years of owning the M90. I had bought it for use with World of Warcraft and it did its job beautifully, but I did have some problems which I will go into. The aesthetics of the mouse are also great.
Summary: Overall, the mouse is excellent. It is comfortable, beautiful, and solid. I especially enjoy the layout of the alternative buttons. There is a small learning curve (as there would be with any multi-button mouse), but once you get it programmed how you like it, your action-packed MMO play becomes...
