At first I was a little unsure when I "own monitor. I was however assured by the company, one can thus use my model (Asus 27" a 27 self-model of standard gaming series).
The arm itself is actually assembled quickly, even if it's initially a bit tricky to find all the screws and adjust. At the end of the monitor is then mounted to the plate. These screwed to the monitor from its pedestal from it and then on the plate. The process takes less than 5 minutes, VESA connection provided (square mount the rack with 4 screws, is available in 2 size formats, both are supported).
Difficult it was to find a place for it. I had miscalculated with my computer table, because the arm and the monitor will need just a little space to be useful swiveled and placed can. After I tested all mounting versions, I gave up first and then mount the rack to a cabinet member. Held perfectly! 3 weeks later the arm was broken by the wood panel. Arm + monitor were too much! Fortunately no damage neither to arm or monitor. Then I got the thing on the massive window sill mounted, even drangehangen an extension and am happy with it ever since.
The flexibility is great! The quality is great! Settings there to be sufficient. Whether you want to adjust your monitor upright or slightly tilted down or up. The arm is everything here!
For me strong buy recommendation, one should note, however, that the total weight is very high and it therefore requires a massive area to fix. Also you should provide enough swing room.
