I hereby claim this to be the official mouse thread! Ill start:Logitech G5 Laser Gaming Mouse. Its amazing, works perfectly on my wood desk. Even has a really cool USb cable, its like rope. IT fits my hands perfectly. It also has this cool thing where you can add litte weights to make it heavier, and you can set the DPI for way too fast, just perfect and too slow.
