Well, be easy with the zipper's, they will blow right out the ends with little to no pressure. The frame I've had no problem with. I've had it for one year, one summer to the next. The roof has three rips in it. These things can all be replaced. It works very well to keep the sun from baking baking stuff you need to store. i.e. lawn mower, wheel barrow, bicycle's etc.. real easy to set up. I'd give it 2 1/2 stars because of the cost and because of the cheap material. A made in China product probably!
