An excellent low budget gamer mouse

Most:
- Correct Weight (neither too light nor too heavy). It is lighter sentence than the Logitech G3 to which I am accustomed for years, and it suits me.
- Buttons of accessible functions, reagents and not annoying
- Optical sensor with correct sensitivity (although it is not laser, it's a small problem which is forgotten on proper mat)
- Roulette with fairly light and fairly quiet crants
- The "Logitech Gaming Software" tool (to download from the Logitech site), which makes the service expected. Are profiles management is not too intuitive, but I do not use it (one profile enough for me for now).
- Cash well without lifting acceleration (essential in FPS type games ;-))

The least (we must find good):
- The sensor is not but infrared laser, although it is not a problem on a mouse pad.
I do not play on a glass table or on surfaces "exotic" ...
- The sound of clicks is not discreet, without being insufferable as I saw on the G100S ...
