I just invested in a new mouse - don't laugh it is a "gaming mouse" by Zealot by TeamScorpion for precision tracking. I cannot imagine why the technical world has not actively promoted the braided fiber cable.
I have tried the wireless mouse and am soooooooooo looking forward to the braided fiber cable.
Just the feel of this mouse is 100% better than my advanced best in class wireless.
Rodents have batteries now? Took me awhile to realize, "Oh, yeah. Must be the wireless ones."
Meanwhile, the other posters are right. I've had both the rollerball and the laser, cleaning them solves the problem 99% of the time. The ridges on the rollers are not part of the mouse, they're accumulated dust, fiber threads, whatever. Pull them loose with tweezers. Rubbing alcohol is the best cleaning solution I've discovered. And do clean the four corners of the bottom outside of the mouse. That causes stickiness, too. May your mouse live long and prosper.
