Great product, more than satisfied.

from Hanson, MA on 01/24/2016 – Verified Buyer

Bought another tv mount extension, but it didn't extend as far as we wanted like this one does and it also closes nice and tight against the wall, plus I love that it has a locking mechanism on it. Very east installation. Would recommend this to everyone!

Good quality

from stevensville, MT on 09/21/2015 – Verified Buyer

Only complaint is the bracket that attaches to the TV has a max of 4.5" mine is 11". I added a 12" x12" steel plate to make it work.

Just what I needed for my RV

from United States on 05/01/2013 – Verified Buyer

I needed a locking TV mount for the TV in the bedroom of my RV. I looked at several locking models and selected this one. It was easy to install, works great for my 22 LCD TV, and best of all, locks flat against the wall while travelling. I highly recommend this TV mount for all RV'ers who need to keep their TV safe while on the road. BTW, we just finished a 2,200 mile trip with the unit mounted and had no issues with it of any kind. Easy to lock and unlock, too!

Happily Surprised

from Surprise, AZ on 07/18/2014 – Verified Buyer

I was not sure this would work for locking the TV well while it traveled down the road. A 24" TV is on the mount and it works fine.

Size and Fit

from Texas on 06/08/2013

Warning! In the product Features section it states Suitable for up to a 32 TV. It does not fit a 32 Visio TV. The TV bracket is too small! My rating is for the misleading information on the web page, not the product itself.
