We used one up in Canada and it was very nice. We had an absolute monsoon of pouring rain. Probably 2 inches in 45 minutes or so no exaggeration. 5 of us started out inside of it but about 15 minutes in water was flooding the ground and blowing in the sides so 3 left for the tent and 2 remained in the clam screen tent. We lasted it out and surprisingly the only reason rain came through the screen was because of the wind. Otherwise it just shed down the sides.
There was some initial issues with setting it up but I think that was due to how it was put away which LED
to one of the hubs breaking. All in all it was invaluable on our trip. Nice play to sit and eat without bugs and plenty of room for 5 guys and their big chairs.
Still not too impressed with those hubs they tend to be fragile.
