They work well but the strips only weigh 2 ounces each making it difficult to balance tires that require 3 ounces. I didn't pay much attention when I ordered them and now I'm pretty sure I buy 3 ounce weights. It's also a small box, and the price per ounce can be double that of buying a large box of weights. If you don't need a lot of weights I think this box is fine although they are pricey but if you need a lot of weights I would suggest looking for big boxes of 3oz strips.
