Has worked perfectly for over a year. Was slightly difficult to find studs but mounted a 22” vizio to the wall and have taken it down for cleaning and using it elsewhere while keeping the arm attaches to the wall. I used my own screws though.
The unit is well built and was simple to install. I mounted it to a stud with 2-1/2” screws which are more than enough for the 24” LED HDTV I have. The mounting of the bracket to the TV was simple usin the supplied machine screws. Attaching the bracket to the arm is super simple and the thumb screws made it quick work as well.
