The only bad thing about them is the really stupid problem. The diameter of the hole that one of the mounting screws goes through is too large, resulting in each post having a wobble that persists no matter how hard you tighten the screws. It's not a big deal as the speakers don't really move, but given the price and quality of the rest of the product it's just an unfortunate oversight. Simply installing a cheap nylon pad would solve the problem.
