I've got one myself, and am in the process of learning to do all the movement via mouse will take time tho.. I figured i will be starting to do that on my resto druid in pvp as it requires the most quick movement If i can get it done well on him, cone and brain control should be easy ^^

sidenote: It's a great mouse indeed. but make sure if you get one you thoroughly inspect it when you get it. Logitech have messed up on quality control a little regarding this particular model, and chances are you may have a faulty one when you first order it (get it replaced ) I bought one from www.overclockers.co.uk who have been very professional and replaced my mouse in 2 days (1 for sending off, 1 for shipping a new mouse). Unfortunately the second model also had a problem (different to the first >.<). Can't wait for my third to arrive ^^

I don't want to put you off, it is an amazing mouse 8| so much versatility and the battery longevity is insane (first one, besides the malfunction had around 50 hours of work/play under it's belt (not back to back ofc :P with breaks - but no charging) and still had 1/3 battery life on it.
just don't throw your old one out immediately ^^ and expect to use it 2 weeks from when you first get it :P
