Not good.  My one leg bent despite the tent being pegged down in a 20 km winds to the point that half way through the 2nd day  the bend turned into a full split like when you bend a pop can back and forth through half of the pole.  We had to duct tape it and cross our fingers.   If these ate steel poles it has to be a tiny bit of steel and a ton of aluminum.  The tent on the first use had to be left at the show since we couldnt collapse it since it had warped so bad, ruining any chances of trying to return it.  Plus side the roof only had a few holes in it from rubbing on the cross beams.  Not any use to us without the tent, but hey.
