Product review (5 stars): Works.
Of course the washing machine still wobbles when it is spinning up, usually, in the case of our Samsung, within a certain range of rpm on the way to its cruise speed.  But the machine no longer walks, or bounces.  It just wobbles, quietly, on the pads.  I'm satisfied.  Next time, though, I'll make sure the washing machine we get has no reviews commenting that it wobbles.  Never had one do it before, and I'm surprised a Samsung would.
