Looks like a smudge. But the one I just found out I would be getting is the 5cent one in the first link I posted. The thing on that one that concerns me is the smudge on the left of the machine going up and to the left of the glass can you see it? I am wondering if that is tape or just some residue left over from a cleaning. That one is supposed to be on the showroom floor and that would be the one I would prebably be sent. He said the 25 cent one needs to be reshopped and tested before releasing.
