This mouse is actually fantastic for me, except for one TERRIBLE FLAW. First the good - it's sleek, the sensor is amazing, it feels bonkers great in the hand, and the thumb buttons are very well positioned. I kept reading a lot of things about the scroll wheel, but I didn't find it distracting at all. I can't really see a use for free-scrolling, but the standard incremental scrolling works quite well.
Now, for the bad. The TILT WHEEL FUNCTIONALITY is absolutely useless if you are thinking of re-mapping the tilt buttons. The slightest, most minimal application of pressure to the scroll wheel will often trigger the tilt buttons. I repeat - if you use mouse button 3, you will FREQUENTLY trigger tilt left and right. This means the tilt wheel is useless if you plan to re-map the tilt buttons (which I personally always do). So, if you are never going to change the tilt wheel mapping - great mouse! Fantastic deal! If you don't want to be moving backwards and forwards in your browser every time you mouse 3, or want to re-map the tilt buttons - DO NOT PURCHASE THIS MOUSE. COMPLETE WASTE OF MONEY
