Summary: The product does what it claims - gives a good PDF or JPEG Image. The ability to scan far away from the computer, and the ease of transferring images from the MicroSD card, is a big plus. A 4GB card holds an awfully large number of images. But, the challenge is to maintain steadiness and straightness of the scanning motion - and for folks with unsteady hands, it is difficult. This is made worse if the object being scanned is not flat, eg., a book.
