I was pleased with the unit. Installation was fairly easy; the only thing that caught me by surprise was that the 3 screws that affix it to the wall required a socket wrench, but once I obtained one it went smoothly. Unfortunately I feel that the two ends are slightly off-level, so even those the wall bracket claimed to be level, the arms are off by a slight bit, so there was an unexpected tilt to the TV by about a degree or two. I'm pleased with the many sets of mounting sizes; if I ever need to switch to a new TV, the mount should still be useable!
This desk mount arm is very sturdy and is well made. I recommend it to anyone wanting more desk space and a lot of flexibility in monitor positioning. I am using one with a 24 inch Dell LCD and the other with a 20 inch Dell LCD. Both are working great, are stable, and allow for a large range of positions and viewing angles. My only desire is to have a taller mounting pole included with the arm. I have the arm at its highest settings, and although it is fairly in the correct viewing height, I will still be placing an extra small piece of wood between the desk and mounting bracket to make it taller. I contacted Ergotron sales directly to inquire about purchasing their taller mounting pole separately, but have yet to hear back after 1 month.
