Query: Great Product, Bad Packaging

I purchased this for my boyfriend who has back pain every once in a while. We would have got an inversion table but we don't have the space. The package arrived in good time but was missing a very crucial piece, the shipping box had an open corner with one piece sticking out. I contacted Amazon and was offered to return it or get a credit. After contacting the company (Teeter) I took the credit from Amazon. Because there is a warranty for parts and service they sent me a replacement piece free of charge. We had to wait about two weeks for it to arrive. It was fairy easy to set up and install and works exactly as described.
