I love this mouse! As a female graphic artist (and gamer), its was a struggle to get a comfortable mouse, that was dual purpose and the right size! This is an affordable, smaller sized mouse, and is perfect if you have a medium/small hand, or just use your finger-tips. If you have a big hand and you like to fit the mouse in your palm/give you mouse a big cuddle, then I suggest you go for one of the other excellent Razers, like the DeathAdder or Lachesis.
P.S the only down side to this mouse is that the scroll wheel acts like a lumpy cog and is a bit noisy, so that might take some getting used to. At the time I purchased there wasn't any Apple Mac software but it still works excellently, (just some of the fine-tuning isn't available). To get the most benefit I recommend you team it with a quality precision mouse pad, (eg. 3M or Razer).
