For the price it works fine though i have to admit it worries me.  It says it can fit a 55 inch T.V, i put a 48" TV on it and it by all means fit, but the thin metal bars which bolt to the TV are obviously bowing under the weight.  I'll give it this though, my TV has hung on it for probably over a year now and it hasn't fallen yet, though i can say each day i am waiting for it too.  The full swing motion is nice works as expected, we occasionally turn it toward the kitchen when we are all in there doing things.  I would give it a 5 star but the thin support bars always worry me so that keeps it at a 4.
