First impressions are that this is a solid bar, particularly at the price point. The knurling is consistent and sharp enough to be grippy, without being too aggressive. Plating and machine work are more than good enough for the intended purpose, and the collars spin freely along the entire length of threads. Perhaps the thread interface is a little loose, but nothing that will cause any issues with wear in my lifetime.
