Dean, I'm sorry, but I feel the Corsair will disappoint you. I bought an M95 and sent it back. Had to pay the restocking fee, but just could not live with that mouse. Did not fit my hand well, weight was all wrong, cord was just in the way, and it was too slippery in my hand. Oh - and a HUGE dislike - the Corsair does not have a free-wheeling mode on the mouse wheel. I'm sorry, but I just hated it.
I've long extolled the delight I have in the Logitech Performance MX mouse. It is simply the best. Fits my hand perfectly, is the perfect weight, is not slippery, free-wheels OR has click-stops on the wheel (wheel locks in/out of free-wheel mode with a button behind the wheel,) and has great configuration software...

Sounds like you already ordered. Wish you'd have got with me first. I hope the Corsair works out for you.
