Query: Poorly responsive junk

i got this mouse to play Bejeweled Twist with (The most demanding game on a mouse that I regularly play). It has a poor response, stickiness and almost impossible to get to respond well, either moving too fast and over-correcting, or too slow and hard to align. It is no better than my 6-year old basic Microsoft mouse. Also, since Amazon doesn't sell it directly, expect problems returning it. Avoid this mouse. Get one you have tried out first.
