I have had this scanner for a year and a half now & am very pleased with it. It is very easy to install & use. The optical recognition software given with the scanner is almost perfect with typed text but useless with handwriting. It also recognises EXREMELY fast (about 20 seconds for a full A4 text page). It scans very fast (sorry, haven’t timed it) using the USB port. You can see a preview of the image being scanned so you adjust the light / contrast / colour before doing the full scan. You can scan in colour, black & white or grey scale. You can change the resolution from 72dpi to 19200dpi. It’s very easy to clean dust off using normal window cleaners. It also has a ruler on the scanner bed so you can see what size the object you are scanning in is. Also if you place a 3D object to be scanned e.g. a Ferrero Rocher, it scans it perfectly showing all its dimensions, it looks like a proper 3D photograph of a Ferrero Rocher. This scanner is definitely worth what I paid for it (£45 from a computer fair) & now it is about £30-£35.
