I checked my order history to see when I bought this greenhouse.  It was April 2020, which means it didn’t make it for a second growing season.  When I went to put it up this year, the zipper had broken, two plastic supports had dried out and cracked and it was totally useless. When i first put it together, it was really flimsy compared to an older one I still have and have used for years.  And my first impression was correct.  It is flimsy, and now just something I have to recycle while I buy a better quality one.
