Has worked well for the last 4 years. Unfortunately, there isn't much UV protection. The material has faded and weakened to the point where rips and tears appear every 30 minutes of use. In the meantime, around 50-100 fractures have been repaired in our department. If I had known this was a problem I would have brought it indoors after use. But that would be annoying since kids use it almost every day in summer. A repair is no longer worthwhile. I think I got my $500 from it. PSA, buy clear gorilla tape instead of expensive vinyl tape. It works just as well at a significantly reduced cost.
