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."
Examiner writes "Does the MadCatz Cyborg R.A.T. 9 wireless gaming mouse live up to all the hype and hoopla it has already received? Is MadCatz shooting fish in a barrel by sending one for review?"
Used to own one but sold it to a friend. Decent, but the mouse wheel click had this terrible softness to it; I could barely feel when it was depressed.
It's not too expensive if I recall, so worth a look.
Never used either one but I have used Logitech G500 (Successor of MX518) and SteelSeries Xai, and I would definitely recommend them. G500 is a bit heavy though.
i have the rat mmo 7, the rat series of mice are truly awesome mice.
