I think more of what I will do with them vs how many time I will use. They are light years ahead of the old 'Taiwan tools' that the chrome flaked off. One area I have had problems is small bits. hex torx etc from set. Non hardened junk... have twisted a few in two on first use. I forget if my metric hex sockets I got recently are HF or Husky, I saw one of the small ones is twisted and I've barely used them.
