How's the battery life. Thinking of getting that mouse also
Battery life sucks ......

I have been using Performance MX 950 close to 3years or more ...
And I need charge my mouse once every month on average usage.
If you game a lot, I believe u will need to charge almost ever week.
Overall it's still a good mouse, thanks to the Darkfield technology.
It will still work on a GLASS Surface ...
But the Logitech Control Center or LCC does not do much on Mac OS platform.
Bought Steermouse for US$20 does much better job.
