I was wondering if anyone here has had experiences with this mouse

I'm actually pretty happy about the batteries. Having to put the whole mouse on the charger is a bit of a pita.

I heard that you can remap the dpi buttons as well, which would be ideal. Are there notable restrictions on what you can remap them to?
I know the setpoint software can have some rather arbitrary mapping limitations.

Also, just what are your experiences with these stealth buttons? How's their usability?
