I just ordered another one of these; my first was in 2015 and is still going strong. The second is to have one handy at another location. I use it primarily with the sheet feeder to scan notes for archive. And it is a bit unique for these types of scanners. If you leave the dock connected to the computer, you click one button to put it in scan mode. You then feed single sheets, each saved to the mSD card as a PDF (or jpg). Then, press a button; your computer will recognize the mSD card and you have access to the files. Nothing fancy here; but quite independent of any computer side software that in my experience, usually disappoints. Now, multiple page documents? I simple use Tracker Softwares PDF exchange, which adds an option to file explorer . Select all files, right click, and select combine. Review the order of the files, one click, you have a multi-page PDF. I have owned several small scanners; but this unit has been the most trouble fee, and most useful.
