if you're a Johnny-DIY poorfag that can't justify buying full sets with 75% overlap, which was me 12 years ago, adapters make a lot of sense. My only socket set was a mixed 1/4 & 3/8 set with a single 3/8 ratchet and adapters that only went up to 19mm. I couldn't justify a full 1/2 set so I bought a rail of impact sockets from walmart that covered 17mm to 24mm. I didn't even own a 1/2 ratchet or impact, just had a breaker bar, and I was afraid of breaking my only ratchet so I'd often use a reducer on the breaker bar to crack tough bolts on my truck.
