Surprisingly good quality. over the years I've seen these sort of boxes in other people's gardens and thought the looked cheap and nasty, often I was right because they fell apart quickly, but these are a different breed. The are easy enough to put together but I would advise anyone doing so to make sure the put the metal stiffeners in their channels before putting the ends on because this box is push fit and once together won't really come apart - I forgot and now have 2 metal poles left over :-) But, like when I bought my shed, I plan to add a few wooden supports to make the thing last longer still.
