Excellent scanner. TOO many different options and little programs that install so I wound up uninstalling most except for the Plustek DocAction application. Double-sided scanning is great; I did my entire 240 concert stub collection with awesome results!
I bought the S400. I find it to be better quality than the old scanner, so it should provide years of flawless performance. The software package that comes with it is great for a traveler like me. I scan in all my receipts and put them in the required folders. No issues! I love it!
This Plustek Scanner replaced an old scanner of the same style. It is at least twice as fast, has no issues with the image being off-register and reproduces images reasonably well. For design work it is way under par, but for document scans it’s more than adequate.
