Mouse with Red Laser Spaz problem.

Hello. My IGN is Gu. I have a problem with my mouse and all my previous red laser mice. Since i run on 3 sensitivity, i have to jerk my red laser mouse into one direction fast if someone is behind me (flanking etc..) But most of the time, it just spazzes and moves in all different directions. And when i record with fraps for youtube videos.. it just looks like i aimbot...... Can anyone help??
