Two of the metal rods were not made in the proper proportion (the metal button that pops up into a hole in another bar each connects to was off from where it is supposed to be located) and were literally impossible to connect to the other two bars that they are supposed to connect to. Hence impossible to assemble. A total waste of money. Possibly the worst quality control I have ever seen.

Bad holes

Poles 1 and 2 don't click together due to poorly drilled holes, the clicker and the predrilled holes don't line up, really should return, but it's for outside, may try to fix the holes with a drill
