Worked great. We Bought it for my daughter’s bridal shower because it was supposed to rain and actually held up during the light rain we had and the winds that came along with it.  But you have to secure it properly. You  just can’t set it up and leave. It has to be tied securely.  We used extra rope and tent pegs. We tied to some trees that were close by. We had it in a back yard that had a fence around it, so that helped protect it from the wind, but it was hit was some pretty good gusts of wind and it held up. The only problem we had was Some of the bars kept slipping out of the connectors so we just stuck a nail through the metal part that came out and that stopped it from slipping out. Just have to be creative that’s all.  I would say the material it’s made out of it like the material they use for a tarp. It was pretty strong.
