I love this bubble. I used it as my “outdoor lab space” for fall and winter. I was able to use it for a year, moving it to mow. I wanted to take it down but it was sort of “weathered shut” and I couldn’t easily disassemble it to move houses, so after a year and a half I just broke it down and trashed it. It was still worth it:) I bet it would last a few years if I hadn’t had to move. 
Lots of interested comments on it too:)
