The R.A.T. 9 from Cyborg is a 2.4Ghz wireless, 5600 dpi wireless mouse that offers a crazy amount of customization for serious gamers. First of all, you get 3 interchangeable pinkie grips and 3 palm rests. The weight of the mouse can be customized by adding or removing one of the five 6-gram weight discs. There are also 4 dpi settings, 5 programmable buttons and 3 cyborg modes. If that’s not all, it looks cool as heck. The only down side is the price – $149.99. Ouch.
