I have been using this scanner daily since I bought it in October 2009, having now scanned around 2000 sheets. I have had no problems with it at all. It is simple to use, quick, and produces good quality (not quite good enough for photos but close) pdf's or jpegs, of small file size. The unit itself is surprisingly compact. The UI gives good control over the features without being too complex. The sheet feeder allows you to scan up to around a dozen sheets at a time, simplex or duplex, with the option of adding more sheets to the same document when the current stack has been scanned. Thus I have managed to scan a 140 page book without a great deal of difficulty. The scanner is good at detecting misfeeds and allows the option of continuing within the same pdf if a misfeed is detected. It will autorotate images if you set that option, though with complex images the autorotation will not work. It will also, with good reliability, remove blank pages if you set it. I don't use the OCR feature which I believe requires Adobe Acrobat, and which I understand you have to pay for.
