Replaced the same unit that was broken when I knocked it off the desk. I has some feed issues like many "portable" scanners. Unlike many of those that are getting the "portable" label it's fairly bulky and cannot draw power from a usb connection and instead has a bulky wall wart.
Would love for it to be twain or wia compliant but, alas, it is not. I does have decent software and can scan to acrobat and a number of other formats.
