TV doesn't want to stay straight. It holds up well enough but tends to move. I can try to position it at the desired angle and tighten it as best as I can before mounting the TV on the bracket. The weight of the TV (new TV isn't that heavy) makes it difficult to tighten the plastic wing nut (or whatever it's called) enough to stay securely in place and prevent it from twisting End spins / falls down.
