I bought this for the wide door, and it is my first greenhouse. It was very easy to put together, the key is to not tighten the screws till you have all sections together. That being said my BF still had to drill out the very last hole. No big deal. The cover is fairly thick. The only downfall is that where I live is very windy. There is no way to use the roll up sides to ventilate. It is a design flaw, they should have just used big windows. The whole entire side comes up and the flap that lays on the ground can't be used to anchor. I have cinderblocks around the entire thing to hold it down. I am getting windstraps for it so maybe in the summer I could open it up. We have had strong winds and rain and the unit has held up. I'm not too worried about it getting hot inside, I think the front door rolled up, will be sufficient for ventilation. We are not extremely hot in the PNW. All said, for the price I am very happy. It does drip water inside the unit, but that will happen when it is closed up and with plastic. Can't wait to start my containers of vegetables!!
