At first, I loved this product - until the first semi windy day!  I had it tied down and the tie downs ripped out of the greenhouse and I found it in my neighbors yard.  It has rips in it and is useless now!  Luckily, it was too cold at night for me to have my plants in it all the time and I did not lose my plants!  I keep my plants inside at night right now, so my plants were spared.  Now I have a useless greenhouse!
