Once I had decided on a projector now had to be a canvas. But since I have no experience with screens, the choice fell on this very favorable canvas, with the ulterior motive: If this is not so great, it was not at least expensive. After 2 days, the canvas was already there and after I (was packaged very well) unpacked and had attached to its intended place, I was thrilled. You see the screen not to which they were so cheap. The screen can be pulled out well, it will remain at the position to which they have been pulled out and can be after the end of use again by a brief pull back curl without problems. Conclusion: Fast delivery, Best price, very good quality, excellent operability!
