The little cold frame was sized as described. My complaint centers on a few things. (1) the little wire tie downs are virtually worthless in my windy location. I will make my own. (2) website does not say you need to seal pieces with PE tape. (3) website does not say you need to seal pieces with suitable caulk. Finally, lack of written assembly instructions (pictures are just not good enough), especially when assembly pictures do not say you have to put assembly screws through the polycarbonate material for them to fit properly.
