I just assembled last weekend, so hard to tell yet.  It does seem to be built well and most of the parts fit together well.  The roof, however, did not fit together well and was very difficult to assemble.  Part of that is because the instructions, as I read in everyone else's review are so very bad.  The descriptions of steps are poor and the pictures/illustrations are even worse.  There are NO extra screws provided and the ones that are provided are very soft and easy to strip the Phillips heads out.  For many of the screws they should have been Allen head or some other type of higher strength head.  I would consider purchasing this again.
