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 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.
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...
Summary: Bought this mouse because I've always had good experiences with Corsair products. SO glad I did. Primarily used for gaming (mainly Dota 2). Mouse has a nice, heavy weight to it, which I've always preferred to lighter designs.
Summary: I am a palm grip user. I have this mouse a few months to get used to. To me using this mouse is life getting hit with bricks in the hand. After a long session my hand was always sore. Also, the side buttons seem awkwardly placed and the software want that great.
