Query: it Broke!

The support ring broke the first time I used it. Fortunately for us, it broke immediately after we installed it. We had bolted it to the studs, bolted to the television and then we moved it around to check the articulation. The ring around the main tube may have been cast aluminum or some other light alloy but it should have been steel. It broke in half immediately but fortunately we were ready to catch the television.It was a pretty important part that failed, you'd assume that they'd have engineered it correctly or at least tested it to see what the failure weight was. Unfortunately I had purchased this mount several months before I actually used it so I didn't even try to enforce a warranty.
