Let's call things by their name. I had a single-arm base which was made of 4mm steel! Amazing base! However, when I took the TV out, the screen would tilt slightly and needed readjustment, and as soon as I put it back in, it would straighten up. This happened because it had a single arm and didn't have a swivel arm like this one. As soon as the base arrived, I burst out laughing!! The base is not to say anything more. Disgraceful. What sturdy construction, what a wonder the gentleman downstairs admired? The base is flimsy, the brackets you hang the TV on are fake!! You can't move it with your right or left hand and see it. I hung a 65" Sony Bravia weighing 27 kilos!! I try to move it right, left, same thing!! I try to move it back, same thing!! It's stuck!! I won't play with the base anymore. Now I'm looking for another base because I gave the first one to a friend and I'm ashamed to ask for it back and give him this one, since the kid has a Xiaomi 55" weighing 8 kilos. Don't make the mistake and get it. It's crap, only suitable for a 32" at most! But whatever you put on it doesn't work, it doesn't move, and as soon as you loosen the screws a little, it's a disaster!! And I bought it based on the reviews I read!! Next time, I'll buy what I believe in because many people haven't seen other bases or simply don't know how to evaluate a base, so be careful what you read!!!! Good continuation
