Query: Pretty Good overall

Mouse is really good overall. I read some reviews from people complaining about it 'disconnecting' and 'cutting out'. Here's what happens, if you don't move the mouse for about 1 second or longer, it will have to move a little bit to 're-activate' it. It's immediate, not like it has to reconnect or anything. I got used to it, but it's a bug that logitech needs to fix, or they were going overboard on power saving. I'd rather replace batteries more frequently (or like me, use rechargeables) than have it cut out like it does.. Other than that, it's a good mouse.
