Worth the $80, but needs modifications to endure the weather. Plenty of videos on YouTube. Everything fit together nicely, instructions were easy to follow. While the metal tubing is very lightweight, the cover and stiching is rather robust, including the zippers. To keep the greenhouse from being demolished by Mother Nature the bottom tubes need to be screwed to a 2"x4" (or heavier) frame and lashed/staked to the ground, (the rope and stakes included would not be suitable to secure a marshmallow in a light breeze). I used 1" wide seatbelt type strapping material and 1/2" rebar stakes. The strapping went completely over the top at each end and through the hoops sewn into the screen. To keep air/wind from coming up from underneath the screen I used furring strips and screws to hold down the bottom of the screen to the wooden frame. In a open area, I would suggest four 'T' posts, about 4' high just inside the corners and tied to the frame for additional support.
I plan to remove the screen during the warm months and allow vining plats to use the frame as a trellis until fall. I will buy another to increase garden production in the spring and fall.
