Query: Malfunctioning Product

I recently purchased three of the Coby digital picture frames. I had intended two to be Christmas presents and to keep one for my self. However, after spending a few hours scanning photos and resizing them per manufacturer's specification, I kept receiving an error for the USB driver when I tried to plug the frame into my computer for download. I phoned tech support, searched the web and even called some tech savvy friends and no one could help me. Eventually I gave up and opened a second one which I could download into immediately. The problem was half of my pictures were grayed out in chunks. I sent all three of the frames back. Very un-user friendly and I would not recommend it to any one.
