There's remarkably little technical information on their website. It even says you cant measure the balance level achieved by putting the wheel on a balancer with the beads in.
Its the perfect product, you can claim what you like with absolutely no way of actually quantifying how effective it is.

Ditto for me. Product claim makes no damned sense... centrifugal force would mandate them going to the HEAVY side of the wheel/tire... hence making it worse???
