what you guys think of horizontal scrolling? I had it on a R.A.T (worse mouse I ever owned), and the idea of using it for situational stuff in games was interesting but the wheel itself was crap, and stuff in general just isn't built for it. This just has buttons on the side of the wheel though and I was thinking it might work a little better because of that, is it any good? I say buttons but it's just to arrows, what is it a sensor something?
