Very inexpensive - possible adaptation difficulties in smaller devices.

Use this wall bracket in connection with a 40 "TCL U40S7606DS. The wall bracket went to mount a bumpy on TV, but also not presented us with major problems.
Very good is the adjustable angle of inclination, so you at little imprecise drilling the TV still can just install.

However, it may be that in smaller devices / projects (depending on the design), the wall bracket on the TV upwards below. In my 40 "it has just worked out so that you do not see the bracket.

Otherwise, the wall mount works perfectly and is very easy to move.
