Only just got this, but an initial test run was very simple to do and the quality, just scanning a newspaper, was very good indeed - full marks on that score. However, the wifi connection is a faff to do, and having waited and paid extra for this I'm not actually sure I'll use it much. It would be much simpler if it was Bluetooth.
I found trade scanners a pleasure to deal with and the book scanner easy to use and setup
