I installed this wall support very quickly without any difficulty. Fixing the video projector on the cross support has not been a problem either; the legs and screws provided are perfectly adapted to 3 points of fixing my VP (BenQ W1300). You just have to be careful to balance the VP, but the installation manual is very clear and well explained this point. Then the attachment of the cross support to the wall bracket is very simple and very safe (no risk of dropping the VP). Finally the adjustment on 3 axes allows a perfect fit of the image to the screen. Compared to what I could see also this support is really cheap and therefore has a quality / price ratio.
