Pros: The mouse is just about everything it advertises. It's a good size for the hand, its quick, moves smoothly with the slip pads on the bottom. Super responsive on screen. Laser precision is just that.

Cons: Cons... The firmware right out of the box when I bought it.. which was going on 4 maybe 5 years ago.. didn't work so hot. When moving diagonally, it couldn't go in a straight line, it moved the cursor like it was going down stairs.. or hitting bumps. Upgraded the firmware, no problem. Now I recently replaced it for what seems like another relatively common problem, the clicker starts double clicking on its own. No fix.

Overall Review: Despite the problems I had, would I buy it again? Hell yes. We as gamers cannot expect our hardware to stand up to constant and brutal usage for years and not take damage. That mouse won me many a battle through many different games. It was loyal and battle-tested. And it died with honor.

Pros: Very quick tracking, good feel in your hand, accurate.

Cons: Mouse wheel has begun to squeak, left side rubber grip is peeling back, cord is extremely stiff.

Overall Review: My biggest gripe with this mouse is that, despite advertising it can be used in wired mode, the wire is so stiff and heavy that the cord will practically drag the mouse towards the edge of my desk on its own. The mouse wheel squeaking is just irritating. For $130, I expected more from razer. I would not recommend this mouse.
