Selling as is, no refunds or returns. The only way I could test it was just by plugging it in, the lights all light up but the few on the right hand side flash more than the left hand side. If eBay would allow videos I took a video to show the button lights flashing. I don't have a PC computer to run this with so that is the extent of testing. When plugged in it lights up.
