Never worked

This looked like a good item. Well constructed, probably easy to use, easy interface. But I could never get past a popup screen that said "Scanner not ready". The computer detected the device, so I know it wasn't a connection problem. However, de-installing and reinstalling the software didn't work, and installing new software from the websites didn't, either, which was all the help desk in Germany could recommend. For this much money, I didn't want to spend days of my time on a device which I didn't believe would ever work. So back to the merchant it went.
