Excellent quality
Bought this to mount a 50" LCD TV weighing 13kg, it's a great fit and is stable and very handy for orienting the TV to where you are in the room.
A bit expensive, but it's worth it to know that the TV is firmly attached.
Be careful with the wall fixing, you really need a brick or concrete wall to fix with the 2 screws provided.
In my case, thick plaster wall, I fixed the stand first to a square board (plywood 2cm) of about 30cm side, to be able to make 4 holes for 4 big screws to better hold to the plaster wall, and it works well, it is solid.
