beads balance my aftermarket wheels better than tire dealers will in 2 years. The only negatives I have is trying to get the Goodyear people to follow the instructions when mounting the tires (they don't like working outside the box) and that some of the inner packing was broken and I was left with loose beads left behind that the installers didn't want to touch. deal with. I'm generally happy with them, although it would be nice to be able to buy the 10 ounce packs in smaller quantities. Using 36 sachets will take time.
