Query: Began to break down and short circuit after a few years

I own this product and it worked great when I first bought it. After a few years, the side buttons went out, then the main button started to tweek out. It would click on everything and anything. . . when I was dealing with files and folders, they would all of a sudden disappear becuase my mouse was clicking on them, accidentally, when I was moving it across the screen. I had a lot of trouble with this because I hadno other mouse to plug in and return things to normal. i pretty saavy with electronics, so I opened it up - there's some very fragile circuit tape on the inside which broke fairly easily - not a user friendly schematic. I wouldn't recommend buying this product .
