The scanner is very reasonably priced. Its portability is excellent. After a few minutes you can get the hang of it on how fast to move it over the scanned surface to be able to get a good image. . Takes a little practice and seems to be more sensitive on high definition settings. In less than one minute of evaluating the scanned images one is able to learn how to move the scanner. I have obtained great results scanning both color and b/w images. It has proved invaluable when the sources of information scanned cannot be removed from a particular area. Images obtained from 3 d surfaces like books have been good and legible. The included software is fairly good. The fact that the equipment does not need to be attached to a computer to be able to scan is an advantage as one can travel lighter. It doesn't work if the microsd is not inserted so be sure to buy one along with the scanner if u dont have one already. Controls are toggle switches very easy to use; included instructions straight to the point. LCD is tiny so if you're above 40 you'll need eyeglasses to see well for the first few scans. You'll memorize the location of the icons for the next scans.It absolutely works. The best thing is the portability. If you are doing document research and taking notes you will love using this. It is a little tricky using it on books but works better then taking handwritten notes on 3x5 cards. I know what to get my college age grandkids. I bought a Micro SD 2G card and don't know yet if this is large enough for large projects but will find out. Neat little product!
