Amazon failed to note Patent Pending on this piece of equipment. It broke after 2 days of use at a preschool. Because it was purchased over the summer (as most schools do) and put together in the fall with the start of the school year, I am being asked to disassemble, repackage and ship the 90 pound teeter totter back in order to receive a partial refund. Called Lifetime to check about any warranty and when pressing 3 for playground, it simply rings for minutes on end. Terrible customer service on both Amazon and Lifetime.
