Good product I use for the first time. The resolution gives a good rendition scan, also appreciable PDF.je or JPEG format that have put 4 stars because the scan is temperamental and turns itself off if you do not go fast enough ... We must make many tests that I did and the result is perfect. to the user manual, it is understandable, although reading it and getting started is easy. The driver installs itself when you plug the cable provided in the box. Do not forget to buy a micro SD card (not included)
