If I could give it half a star I would.  We did everything according to the instruction manual and then added additional anchors to be on the safe side. One day of 15 mph wind gusts and it was ruined.  It literally lasted a week.  And their customer service is HORRENDOUS.  Every time I’d send an email for missing parts (to top it off), they never replied unless I called.  Total waste of money.   I’m so disappointed.  I’m still trying to get a response to my warranty request and nothing.  Not even a peep.  DO NOT BUY THIS GREENHOUSE.
