I hesitated because of the low price, I do not want to take the risk of dropping the projector (Optoma HD50 a 3/4 kg) for some savings. In the end, I'm doing well order it, it's perfect. Certainly a bit complex to assemble with parts to assemble and more than mild form, but it remains relatively logical, not too much risk of being wrong. In the end I secured my projector on the ceiling, the support is white, clean, it blends into the background (see photos). I used the short stem. Here is a picture of the assembled unit. For the price, 4x cheaper than other leading brands, nothing to complain about!
