Summary: Reading the reviews, I cannot believe the nonsense that I read so I decided to write my own review and answer the ridiculous points made by the current reviewers. I have just bought this mouse and I am very happy with it.
Summary: After trying a number of "gaming" mice ove the years I finally went back to the simpler is better motto. No on the fly sensitivity no daft lights, just simple and effective. Works well has no input lag. The thumb buttons are positive in use and the wheel is firm but quick.
