Minimal instructions with product. A very complex interface suitable perhaps for IT engineers, but of little use to the amateur. Zero response from enquiry on the website. Zero response when emailing the technical support line (after they politely answered from Germany, suggesting I use the English web interface that had produced no results). I suspect that this is probably a very good product, but suffering from an almost total lack of documentation, support or response. I wonder whether someone else's software might interact usefully with it and be easier to use. When I have used it it has produced very good results. Plustek please note!
