OK, I have to say we haven't put this together yet. The rating is for the value and pricing. I shopped greenhouses everywhere, and this is hands down the best price and lets not forget the NEW plastic material, is guaranteed to stay clear. It comes with those ceiling windows which are very important to have in a greenhouse, you want your greenhouse to have as much outside air as possible. The size it fantastic on this, I am hoping to buy another one soon, and yes I mean this one. I have learned that WF stands behind what they sell, if you have an issue? It takes a call to someone from there great staff to help and so far they have not let me down, every issue I have had they took care of it quickly and painlessly; I can honestly say they are the only online store that has been consistent in the way they treat people and the way are so quick to fix a problem. I love WF and recommend them all the time!
