1st product from Monoprice that I have not been happy with.
The brackets were easy to install and appeared to be well made. However the way they are designed they flex when you swing the TV to the left or right. When the TV is in the center position it looks great and level. Once you swing the TV to the left or right it changes it level plane no leaving you to look at a tilted TV that is no longer level.
I have my TV mounted above the cockpit of my motorhome. This mount lets me keep it high out of my way when going down the highway, it lowers it just enough so that I can view it at a more reasonable level when watching TV. It works great, has a nice adjustment to be able to handle different weights of TVs and the price was wonderful.
