Summary: This mouse is very good. It has just the right amount of buttons and the adjustable DPI is very useful in game. The matte finish on the mouse keeps sweaty hands from sticking which is also a plus. Overall I like this mouse very much.
Pros: Coming from someone who has owned the MX518 and 2 G400 (one with PID and one is S/N), the G400s is an improvement on something that was already great to begin with! From the G400, the wire is now reinforced, and the DPI has slightly been improved. I've had no problem with it since!
