Extremely strong mount, made of heavy-duty metal. I gave it four stars because I tried installing it with the hardware for a curve mount and the screw was too long, so I tried to screw it in a little more and it broke off inside the tv. now I have it mounted with only 3 screws using the hardware for a flat mount (which worked just fine) but now I have to either get that broken screw out or return the 34" ultrawide Monitor for a new one since I've had it less than a week. I'd hate to return it for that but if the screw extractor I had to buy doesn't work I'm going to have to..It isn't easy to maneuver, I should mention that. I also recommend not putting the vertical and horizontal arms together until you mount the horizontal arm to the back of the monitor and the vertical arm to your desk. then I recommend slipping the horizontal arm on and tightening it. it seems to be the easiest way to maneuver the pieces since they are so darn heavy.
