I used the same thing before. Since the bearing is not inserted, the shaft body wears out, and the ball comes off at the end. However, I think that it is a product with high cost performance. Bearings also have bearing life. For cost reasons, this item is good.
The painting of the round part was sloppy and there was garbage in somewhere. When I got crisp with garbage claws the paint came apart. The circle is also distorted at the top. There is no problem in function. Is the price so expensive, is not it? It can not be used when driving normally. You can use it when putting in a garage or back.
