The projector is highly recommended. The pictures are clean and sharp to recognize. Above all, each new image of itself provides a sharply. This is in slide lectures very beneficial. Painfully this Bildchen- is Instructions. I had a problem with the more points because I imagined when on demWeiterschalter an arrow for forward and one for reverse is it, then I press the forward arrow for front and the back arrow to return. Would be logical. But on closer study I got with that pressing forward and a long press is backward. Now it works.
