Don't use any of them. They can't work. The best you can do is not make it worse.
Just balance your tires and wheels for real. It's not that difficult or expensive.
Even if the claims were real and the demos were not entirely misleading (to be polite), the wheels are not balanced at all speeds under all conditions.
Dyna Beads work well and have for us many years. They save having to re-balance when the tires are worn. The filter in the valve stem does work for the external TPS. As far as erosion the beads find their spot after the tire is rolling and stay there. We have them in over 50 tires currently and they have saved us thousands of dollars over the years.
