Query: Flimsy junk

As some other reviewers have noted, the welds are weak. For me, I tried to put it on a cube wall that was well within the stated size parameters. I did not use undue force but it broke at both welds anyway. Considering that returning it would cost nearly as much in shipping as I'd get back, I tossed (scrap metal recycling) it.
