I bought this mouse with high hopes, as I was looking for a laser mouse. Unfortunately it proved to not be what I a gamer, was looking for.
For an internet user, who does not game at all, this mouse is great – it tells you when you have instant messages or email, and has a plethora of buttons.
However, gamers will not be satisfied. While a high-demand game is running, this mouse will lag so much the game becomes unplayable. Also, it chews through a set of batteries in a week of use.
If you're looking for a laser mouse, I suggest the Logitech G5, although slightly more expensive – it will serve you much better if you game.
