Had to scroll way too far. These things were built to last. Get one of these OP, unless you need better ergonomics like a vertical mouse or a Logitech trackman. (The red imo is much better, but requires frequent cleaning if the ball/contact points and will only last a year or two of heavy use before the switches start to double click and stuff...but so will the oddly highly recommended deathadders. Hell, I often got 6mo if even out of those.)
