GodisaGeek: " It will take some time to set up just right, and then it’ll take some time to get used to after that, but once you’re used to it you won’t be able to go back to another mouse; once you get used to it, using the R.A.T. 9 is like putting on a glove, it just feels “right” in your hand. Speaking about feeling “right”, one of the major downsides to this particular mouse is the fact that it’s for right handed people only, there’s no reason for a left-handed mouse user to get the R.A.T. 9 at all unfortunately, it’s not going to be comfortable and some of the buttons are going to be practically unreachable. If you’re right-handed though, go for it, it’s one of the best mice you’ll ever have the privilege of getting your hand on."
