Required a number of tightening for 27 inch screen, but otherwise it's good and height stayed in place. May need further tightening I suspect, will see how next few weeks.
Although it was a little tricky to mount this on my omnidesk. i am very happy with the end result. Picture as proof.
Sturdy and perfect ! The clamp have option to reach deep tables. Assembly is quick and easy with tools provided. Ninja delivery service is good and got it the next day after ordering.
Installation was really easy, everything was very intuitive. These are solid arms for the price, I love the adjustability! Delivery was very fast, came in 2 days. The only downside is that for heavier monitors (3 kg and up), the hinge sags a little bit even after tightening the hinges.
