Query: Disappointing

The trampoline is very squeaky. A spring is not hooked properly & it seems impossible without some time of tool to fix it. I received this product & received only 3 of the promised 6 DVD's. None of the DVD's work. I wanted to return the DVD's in exchange for working ones but Amazon would not let me do this. The only way to exchange was to send back the trampoline & the DVD's. This is incredibly inefficient, a waste of gas & resources & a huge cardboard box that will sit in a landfill for thousands of years. A simple envelope to exchange the DVD's would be much more efficient & environmentally friendly.The trampoline does not easily fold up for storage.
