This is easy to assemble and mount your TV on (as long as you have the ability to drill holes accurately into your walls.)
There is a lot of adjustment and the TV effortless glides into different positions.
The wall fitting easily took my husbands weight of over 66kg. We have a 47" TV attached which weighs about 23 kg and have no concerns about it's ability to hold it.
There is a very slight 'droop' down from the moving parts when it is extended but nothing to worry about. We only notice it because we were fitting it to be mm perfect above a speaker, if we had known we would have put the bracket just a few mm higher.
