Query: Never worked properly

I have owned mine for a couple of years, and it's never worked right. The "Safe Sense" technology has always detected jams when there aren't any. I have always had to fiddle with it to get the green light on for shredding. The switch to disable "Safe Sense" is not functional. For the past two months, nothing I seem to do can get the green light. While I invested in a better shredder for my office within months of purchasing this one, I've kept this one at my desk as a personal shredder. It's now going to get thrown away. I guess I got a lemon.
