If you have 1/4" drive easy-to-read double detent sockets, check your 5/16" and 8mm sockets. I bet $20 you have bad detents. The inner secondary notch was missing on all of my short/long 6pt-12pt 5/16" and 8 mm sockets. (The groove is machined all the way in) The ratchet still holds on to the socket, but it kinda slides in and out little bit, I noticed it while using my 8mm, then checked all of my sockets...
Also I have 1/2" drive metric regular 12pt easy-to-read socket set ranging from 9mm to 36mm (3 sets combined) double detent (some of them is what craftsman calls 'double marked'). Yep, you guessed it I have the inner detent completely missing on 9-11-12-13-14-15-16. The machined groove runs all the way into the drive end.the ratchet still holds on to it, but the positive 'snap' is not there, it just slides back and forth, especially with the extensions.
Also, strange enough, I have the inner detent machined way too far away from the outside detent (it was way too inside) on 23-24-25mm sizes. The inner detent is there, but it's far too deep. basically same symptom as the missing detent, the socket just wiggles around and slides in and out especially when used with extensions. (craftsman extensions that is)
So the people who have bad experiences with double detents should take a closer look inside the drive end. Maybe you got the ones with the missing inner detents, or maybe the ones that are machined at the incorrect depth.
I'm not even going into what the inside surface of those gun grey chromed double detent easy to read sockets look like... Makes HF pittsburgh sockets look like snap-on! They were all kinds of stuff that looks like bird droppings in there. You can literally cut your finger by just running it inside the socket... But I don't mind it, I see it as craftsman's new innovative idea: non-slip surface inside the socket so that it won't slip!!
