Wireless Mice

So I just got my laptop, a Malibal Lotus P150SM, and I need a mouse for it. Logitech has had their G700S for a while, and they just came out with their G602, which has massive battery life. 

Anyone have experience with either one, or another wireless mouse?

I'm not even going to consider and Razer mice, the receiver is way too big. The Logitech have the micro receiver, which is optimal. Wired is not an option.

I really liked my G700 apart from the battery life and the dual mode scroll wheel, but maybe the G700S is improved on the battery life and the wheel is a matter of taste. The shape of the G602 is a little bit wierd but I'd lean towards it. I hope they make the G600 shell into a wireless with the G602 technology some day...
