Question: Can it be installed on dry wall? or is it just for concrete?
Document: It is a tight back there and a little extra space goes a long way.Now I know this may sound petty, but I have two issues with it.1) The bracket comes in two pieces. After screwing it together its feels solid, but I would have preferred a single piece. It still sturdy on my wall holding my 30lbs LCD TV.2) The Dry wall anchors ARE PURE CRAP because they are concrete!!!!!!!!
Lots of extra parts included. Hard to adjust the tilt once installed, but I think that is inherent to a wall mounted tv.
Works great, easy install we just installed one for my mom it made #4 for us. Would recommend if you are not looking for bells & whistles & just want the TV on the wall.
I bought this product heavily on the premise that it is #1 or one of the best selling TV wall mounts on Amazon. I would not buy this product again, and in fact I am looking for another wall mount soon.Ownership: 2-3 months now, been installed for over 2 months.
I like it . It very easily to installed . The quality it good . It fit my tv , have no problem at all. The delivery is very fast. Thank you.
Yeah they are BAD because they are the wrong ones!!!! Go to you local hardware store and pick up some Good nylon dry wall anchors and Pin or Oval Head screws for a couple of dollars. I am mad because I had to buy extra parts. Yes it was a couple of dollars, but still I had to go and buy extra stuff.All and all I am satisfied with this wall mount. Besides those two minor things, it is a good investment and would buy it again.
Great wall mount, durable
It works as it is attended to do. I am happy to see my tv on the wall. It creates more space.
Very nice TV wall mount for the price. Can not beat it. Highly recommend it and it is within budget.
I paid very little for this mount and it is just as good as those expensive wall mount at electronics stores.
Answer: I have it in drywall with a 42in tv.  better to find a stud for at least one of the screws.  But if you can't, I've switched these type of anchors http://www.homedepot.com/p/t/100391938?langId=-1&storeId;=10051&catalogId;=10053&N;=5yc1vZ1xhv&R;=100391938.
