I have had an original Steelseries Sensei for several years, and mine is finally dying. I've done a lot to try to make it last longer, but it no longer works on my black mousepad, and it's no longer accurate enough for aiming in games. I've been looking for a while at different mice from different brands, and there are only two features that I really need: the fully symmetrical shape, and the damn scroll wheel. The old Sensei has a really good feeling to the scroll wheel that I've come to rely on for accurately switching weapons, because I clearly feel every time it scrolls, and I never scroll too far. So far, I haven't used a single mouse that has this much tactile feedback in the scroll wheel that allows me to use it more like arrow keys than a button. Does anyone have experience with this mouse, as well as another one with the same feel to the scroll wheel? Any help would be appreciated.
