" as they should be" is pretty subjective, to the individual, except for what works mechanically and what is cheating/jerry rigging, etc, that WILL work but not for long, I'm far from a professional mechanic, but I understand theory, and I buy and sell cars for fun, so I have experience in what holds up and what burns up. What is right for one is not always for others, have to keep that in mind before being judgemental, but I sure like that cordless ratchet I saw on here!
