I bought this mount for a 48" Samsung TV (weighing about 30lbs) without realizing it was the wrong VESA mount (400 x 400 mount but 600 x 400 TV). I contacted the company to see what my options are. Instead of sending the product back, they sent me an adapter for free. Once I installed the adapter mount it worked great. I would definitely buy from this company again. A note for those installing in drywall: don't use drywall anchors, they won't work. If you can't hammer two studs into the wall you can always take a piece of plywood (I used a 28" x 10" 1/2" thick board) and attach it to the two studs. After that you should be in be able to easily mount the TV bracket on the wall wood.
