I bought this mouse two years ago along with a set of skates and the Steelpad S&S. It's been through a lot with my play frequency and still works like a dream. the side buttons are well shaped, positioned and sized. the weight is pretty good while some people prefer a heavier mouse, this seems just fine. I recently upgraded to the Logitech G5 which i prefer because of the shape and customisable weight. However there is little difference and the only reason I now use the G5 is because it looks so much cooler :D
