I think this is kind of like how some people complain that Apple USB cables are pieces of crap that are always fraying and breaking after 6 months, while other people use them for years with zero issue.
It really depends on how you use it, how you assemble it, how you disassemble it, is it constantly swaying/weakening a little or is it securely mounted to a wall, do you constantly slam the cubby door or drawer shut or are you gentle? I think the assumption should be that it won't last a move, but that you can get lucky through a combination of chance and care.
