Query: Returned - defective

The bottom brackets depend on a small tab that sticks out to hold them in once inserted. Unfortunately mine was defective and would not stay in. Poor quality control, poor execution, poor design. I knew I was going cheap but I hoped it would work. I have another stand from OnStage that has the same design and works fine. So it's hit or miss.
