Just put it up and the first rainfall we had, water accumulated on the top and it collapsed.  The tent is fine and didnt rip, but the frame is bent.  This with No wind at all. . .just rain.  I managed with a struggle to push the bent frame back up, but now the canopy is crooked.  This is not made right  It should have been designed to allow the water to run off.  IWaste of time setting up.  Will call the company on this.
