The support is very well done! I had some doubts at first about stability, but finally, I have nothing more to say. Simple: once mounted and tightened properly, I did switch the entire office, pulling on the handle bracket. That is, if it wanted good. Concerning the placement of screens, maybe I got caught badly, but it took me a second person. I preferred all up, shake and turn, before putting. So to see.
But otherwise great product. Once all tight, I do not think there is a risk that anything falling! But do not forget to check from time to time that everything stays in place. You never know!
The only thing I have to complain about is that it loosen a screw in the back to move up and down the vertical screens. Otherwise level orientation screens, nothing to say.
