This item was delivered to the incorrect address. I received it a week after notification that it had been delivered. I’m fortunate that the occupants of the wrong delivery location decided to bring it to us. It was completely unpacked and parts missing. I don’t know what the repercussions would have been if they hadn’t brought it to us. Wayfair has been great replacing defective items but happy I finally have the greenhouse because I may have been out a fair amount of $ . Thank you to the couple who took the time to track us down and deliver it. I won't get the opportunity to use it for starting plants for several months but will revisit and likely upgrade my stars. 3 stars isn't a reflection on the greenhouse, it's a reflection on it being delivered to the incorrect location. The greenhouse is solid, double walled as described and I can't wait to start using it.
