So many gaps. Between walls and roof floor and walls. A lot of the screws don’t line up with the holes. Thin metal pieces are warped and would not align with piece it was connected to. 
Too many ways for the weather and pests to get in. Had to buy silicone caulk to fill gaps. Lots and lots of caulk. And there is a 1” gap between the doors. There is no way to fix that.
it’s not the best quality. I bought it because it was inexpensive. But really quite disappointed.
