Needed to fit cheap tires on a truck but I'm tired of the prices they charge at tire shops. I have a HF tire changer and a nylon tip tire changer (Mojolever) and now this balancer too. I balanced my truck tires and am happy with them up to 80mph. I'm pretty sure it's not perfect, but I've just saved a lot of money for a car that I'll never drive past 65.
