My first review was while snow was on the ground so was not exactly practical, however, I finally got it erected a few weeks ago but had not had time to prepare the ground so it is sitting on paving slabs not the gravel bed I want.  It does take two people to erect but is relatively simple and the plastic cover is very simple to install.  I have a small greenhouse with a pointed roof so it is difficult to get the plastic over, with this greenhouse the curved roof ensures the cover slides over easily.  It is larger than anticipated so the few plants I have look lost inside.  One word of advice, buy a spray can of chain oil and spray the bolts and joints to minimise corrosion, my small greenhouse corroded at all the joints.  I will take the cover off for the winter because these structures are not designed for a snow load, I have seen too many car structures, which are similar design, collapse because the snow was not removed.
