i have extenstive experience with wheel balancers when i purchased new or remounted used tires. . it's called the tire shop. one thing to remember is to buy top quality tires with a life time warranty that includes balancing and rotating anytime. . if the tires give you any vibration when newly mounted take them back for a rebalance. i recently did this with a new set of mich. mtx when they were not smooth running down the highway and also the extreme amount of weights on each wheel (3/4-1 oz). they rebalanced the tires and remounted one, now i have 1/2 or less on each wheel and they run extremly smooth. .
i think of snake oil----- if they were so good you would see them on the big rigs and or on some of the exotic forigen cars. .
sorry for the apperance of a slam but i hate to see anyone taken for a ride. just my opinion
