I installed the TV at a 90% angle to the couch and this mount allows us to easily pull it out to watch and tuck it back against the wall when not in use. 

It extends easily and allows a good angle off the wall with a 32" TV. 

It's not rock-solid and I have to lift it a little to get it fully flush against the wall. It's sturdier than could be expected for the price. 

You should measure that your vertical wall stud is in the right place before purchasing since it doesn't have horizontal adjustment that you'll find in the multi-stud mounts. Your only option is to screw the center of the bracket directly into the vertical stud, unless you first build in cross-stud supports.
