Initial results are good, although the item is so lightly built that I may weight it down with cinderblock.  When assembling, examine the tubes carefully.  Some of mine were slightly deformed, and they do not fit into the joint pieces well enough.  In one case, the edge of the tube was slightly bent back, and it hooks on the inside of the joint.  those pieces can no longer be disassembled.  The metal tubes are light gauge, so you can bend it back, but you need to notice before you put the parts together.
