This laminator received in excellent time, proved unable to immediately laminate A4 or A3, and whatever the thickness of the sheets fed. Indeed, only a quarter of the surface of the documents was plastic and studded with more empty areas (actually full of air). So I have to lament the destruction made paper documents to be protected. This device (aesthetic incidentally) is not only invalid, but also dangerous. Only its price is attractive, but I see that I have my money ... By the time I returned to my charge, that I waste time, which returns me one that works disastrously, I prefer to go buy another one elsewhere, that works! I understand that it's too bad for me.
