Rated 4 out of 5 by from Great Hardware software need some improved UI The quality of this scanner is brilliant along with the two sided scanner it made digitising my old documents and photos a breeze. The interface is a bit data and using on iOS device leaves a little to be desired but at the end of the days it’s functional and does want it is suppose to do.

Rated 5 out of 5 by from Great product. I hesitated before buying this but I am so glad that I bought it. Compact, lightweight and easy to use. It is very quick to scan each page and the quality is excellent. Only negative is that it doesn’t have a carry bag.

Rated 5 out of 5 by from Hyper pratique J'utilise occasionnellement l'appareil, mais le côté pratique de ce scanner me pousse à l'utiliser de plus en plus, car il est plus pratique que les scanners d'imprimantes qui ne font pas le recto-verso.
