i have a set of 3/8 and 1/2" drive HF impack sockets with the black phosphate finish.
i'll tell you. I've never broke a hf ratchet, breaker bar, socket or air gun.
when I'm grabbing for a socket to do soemthing.. if my hand don't fall on an impact socket fast.. it grabs one of the plain chrome ones.
i've had my 3/4" and 1" gun blazing away on thos eplain chrome sockets taking big stuff loose.. cuz i only have the plain chrome in the 3/4 and 1" size.
like I said. ain't never broke one.. me doing pull ups on a 6' pipe onthe end of a big breaker bar.. :)
