If you look carefully you will see some brackets are advertised at different prices for different size TVs however the bracket I bought was the same one for all the TVs, it just they list is under three different size categories with three different prices and therefore you just pay more for it if you choose a bigger TV! I phoned them up and pointed this out to them, the lady said they were different as they were better quality to take the heavier weight of Tv etc. I pointed out that they all stated 50KG
My bracket turned up with instructions missing and was an obvious return from another customer. The bracket was actually out of shape and one can only presume this was poor manufacturing.
