if whatever you are using does not have time to redistribute the media for the imbalance it is of no use. i.e., transitioning through an imbalance quicker then the media is able fix it.

i've heard some of the liquid stuff gells up or slowly moves around and can get out of balance.

i have the mercury filled discs on a truck and really like them.

i have bead filled discs on an enclosed trailer, i'm sure i really like them.

i'd put some on my jetta if they were available, i'm sure i'd like them.

same with the fluiddamper balancers, good for steady state, not so good for racing.

i've never used the loose beads in a tire, but a guy at work put something like anti-freeze or a gel in his tires, when he found out it didn't work, he took it to the tire place and they were not too happy about the situation.
