the tent is 100% ok
the structure takes the first time as his time (about 1 hour) and you should build it with at least 2 people.
The second time we have then used about 35 min.
space is great and the island in the middle reaches of a round table in normal size plus four chairs.
ventilation is also great, each side has an air hole in the roof and you can also remove protection so that can pull the warm air at the highest point.
we have the tent and a durability test subject in saachen rain.
ca 4 hour under irrigation (what a heavy rainfall like) and it's all remained dry.
I myself will treat the tent despite everything but with a waterproofing agent.
Otherwise, I would recommend to anyone who wants to several people camping times.
