Query: BROKEN BY DESIGN - A true piece of junk.

Bought this thing expecting a miracle. Did not expect a piece of junk. It's cheap flimsy plastic (why not anodized aluminum for a $240-$300 device like this?). It TURNS OFF after every scan (absurd). It TURNS OFF while you are DOWNLOADING pictures over the USB cable (ridiculous product design).You also have to specifically buy san-disk brand mini-sd memory or it will not work. I had a nice Kingston piece. Did not recognize it. Nice to let people know ahead of time.Sorry, this thing is pretty much a rip-off. How these guys get away with this junk is probably BUYING OFF Ziff Davis PC magazines and relying on the lazy folks who do not return this broken-by-design piece of junk. EASILY THE WORST DESIGNED, WORST QUALITY ELECTRONICS DEVICE I HAVE HAD THE MISFORTUNE TO WASTE MY TIME AND MONEY ON.
