I use a gaming laptop which I am completely new to pc gaming. I am using the Razer Naga mouse which is AMAZING but the 12 buttons on the side of the mouse I cant use the 1-9 buttons it says keys are already assigned. Anyway using the laptop keyboard for more than an hour gets uncomfortable. I was looking at the Razer Tartarus gaming keypad. Is anyone using is and does it work correctly with no problems? My biggest thing I want it for is for moving forward, back and left and right. Just want to be sure before I spend $80.
