I use it for 2 months. It arrives with a cassee room at the tip, making it impossible to mount suspended without risking it falls any time. After several emails we finally sent me the replacement part ... without any explanation biensur and very difficult to replace because the renroulement mechanism is bound. Morality, it is no longer totally renroule and must complete by hand the last 50 centimeters. We can always say that I could send it to my charge ... ... so given the size of this thing ... it cost the same price of the article ... Biensur the size / price seems tantalizing but obviously Quality is not the appointment. The screen remains veiled which distorts the image and is very unpleasant to use. Given the price of a projector and the quality you expect, I find that this screen is not the height and I regret this purchase and would recommend the know except for those who prefer the size has the quality, but knowingly.
