Good product overall. Fast delivery, the material is very well conditioned, a little surprised by the lightness of polycarbonate sheets but the whole is consistent with the description. I had seen in the comments of mounting 6:00 I did not believe too ..... hey if !!! Do not expect too much (within botch the operation) do much better (and even six hours without finishing). The beginning is laborious (we want to give up after 20 minutes) but in the end when you attack the sides everything becomes simple and makes easily. Do not rely too much on the very explicit instructions (not always easy to see the direction of fitting of aluminum profiles, watch out for black caps they must position before assembling in particular). The pins to secure the plates are not very aesthetic and not at all practical to ask. The door requires some improvements not to bother each openings I understood the usefulness of hooks (in the bag with sardines) to secure the clamp to the base after having drilled and screwed :-( But ultimately this greenhouse (once pegged as slight) remains very good given its price (with a base) which justifies my 4 stars.
