Review on MUNBYN Portable Scanners: Fast A4 Color Page Scan in 3-5s, 300-900dpi – Includes 16G SD Card, Easy Photo Transfer to Computer by Guerdon Draper

This is a cheap imitation of the American "iScan" scanner. It scans 1/2 inch, after which the green scan LED turns off. I tried to do 22 scans but it only came out 2. An example of hackwork was that function 4 is marked as a "button" in the manual, but "time setting" and "format" of the so-called "buttons" are little HOLES! I could put one end of a small paper clip in two holes and hear clicks, but a HOLE is not a BUTTON! I tried 22 times to get the scanner to work but was only able to complete 2 out of 22 scans. When I advanced the scanner about 1/2 inch, the light went out and the scan stopped. The scanner's green "on/scan" light will move about 1/2 inch and then stop. The scanner is clearly defective.
