Summary: The scanner did install without any issues on Windows 7. I want to note that it requires a pretty long (~1min) warm-up period so the color temperature of the Cold Cathode lamps is controlled. Unfortunately they aren't using LEDs in this model. I give only three starts because of the manufacturing issues of the glass plate. I detected some spots on the surface and ordered a replacement model. This had also a couple of defects on the glass. This might be only bad luck but.
Not perfect but entirely adequate for my purposes.

Summary: Had to return the first one for an exchange as the scanner glass has dust particles attached to the underside. There's no way to clean this without disassembly. Shipper was flawless in arranging for a replacement unit. The software leaves a lot to be desired. Basically you have 3 bundled programs to chose how you want your scans to be processed. Frankly I use Picmokey and Photoshop for all post production scans so non of them were of any use to me.
Summary: The item was delivered within the time specified and was as described in the 'blurb'. I found that the multi-language instructions cumbersome as they are printed in a single column for each language on one very large sheet of paper which had to be fully opened to read. In my particular case the description of what happens--screens and dialogue boxes etc--in the instruction sheet didn't correspond with the OSD. The instructions were not too user friendly.
Summary: Und täglich güßt das Murmeltier. Es ist nicht mein erster Plustekscanner, und deshalb wollte ich das Gerät auch nicht kaufen, Aber Buchscanner gibt es nicht viele, es gibt zb. noch Microtek, aber die Hompage von denen ist nur auf englisch und nach langem Nachfragen erfuhr ich dass der die Seiten nur in der Texterkennung dreht. Also doch den Plustek.
