Reviewed my package promptly and it was a nice product but ended up being a little to small for my application. Would definitely purchase from seller again though.

*by C***E on Reviewed in the United States 🇺🇸 on July 18, 2016*

This mount appears strong and well made.  And it locks in the closed position as advertised.  Unfortunately, when it is in its compressed (closed) position it measures nearly 3" deep from the wall to the TV's mounting surface.  This dimension is not mentioned in the ad copy, or I must've missed it.  In either event, the dimension was not acceptable for my application and so I returned the unit.

    Must have for replacing old TV's in RV's and Campers
  

*by D***. on Reviewed in the United States 🇺🇸 on April 27, 2017*

I've installed these in two used motorhomes now.  Both of my rigs have had old fashion box TV's in them when I purchased them and one of the first things I did was replace the TV's with flatscreens.  The lock on this mount keeps them from flying around while you drive down the road.  It's a must have.  Don't try to use one designed for a home.If you have a camper/RV, the nice thing about replacing your old box TV's with mounted flatscreens is this you pick up additional storage where the TV used to sit.This size was perfect for replacing our bedroom box set and I store towels and blankets where the TV used to be.  I have a larger one for the front of my current rig and now store an inkjet printer/copier where that TV used to be.
