They 'work' but hold the pole very firmly. Due to the ratio of holes in the TV and holes in the soundbar, the vertical parts aren't completely vertical. Even if this were the case, there is only one mounting point on the TV and therefore the entire assembly "wobbles" when you move the TV and won't stay level unless you level it slightly with yours after each movement hand in. So although it's firmly mounted I'm not afraid of it falling off, just not as rigid as one might expect in my case.
