Query: Piece of crap

I got this Microsoft mouse and followed the directions, which were to install the software and plug in the mouse. The mouse arrow would move, but wouldn't open anything, or check the boxes on their licensing boxes. I went back to my old mouse and the lovely Microsoft software had screwed that up so it didn't work either. I went out to Microsoft's support site and it took half an hour to get signed up for their system, only to have it not recognize their own product id. I started to go with their paid support service, but was unwilling to pay them 3 times the cost of the mouse to use their service, which probably wouldn't work any better than their mouse, software, or support site (I'll pay more to get a local company to fix it). In short, their cheap mouse screwed up my system so it can't be used and then they want to profit on their screw up and possibly fix their error. I'd pass if it says Microsoft.
