Summary: This is a really nice, easy-to-use, affordable mobile scanner for black and white PDF files. The only issue is that the software that comes with the unit scans HUGE files (1 black and white page = .7 MB), so scanning and emailing several pages quickly becomes problematic.
Summary: This is our third Plustek scanner, and this one was purchased to replace an older model that eventually broke after years of faithful service. Sure, we could buy a flatbed scanner, but they take up a lot more space and in my experience are more fragile.
Cons: The software is terrible, unusable, and incoherent. These do NOT produce scannable PDF, just an error message that "font is not recognized." Feed tray is simply ornamental, this will NOT scan multiple documents automatically. Worthless.
