Geez that sucks. I was already planning on it, but this confirms that I will first have it tested fully in the store when I pick it up.
I've had too many products show some failure out of the box and I hate having to drag it back to the store.
I even had one time that I bought a new audio device, turned out to fail right away when I installed it, went back THE SAME DAY, and the assholes wanted to send it in for repair under warranty (which probably meant waiting for 3 weeks or more) ! I made a lot of fuss (and I know my rights) and demanded another (tested working) one in exchange instead. Sad that I needed to make a lot of fuss before they gave in.....also the last time I bought something from that store.
