Query: After the coolness wears off, it's a big disappointment

The mouse wheel feels nice. The whole thing is a good size. I play with the retractable cable often and it is just fine after a year.However, it makes the cursor move on its own. And scroll too. And the cursor jumps too. Not constantly, but just enough to drive someone insane.It also can't handle small movements. It seems like it doesn't always register it. I am not using it for Counterstrike or any kind of image editing. Just day to day movements and it just gets stuck sometimes.
