Hey guys-
I have more first hand experience to add, this time on the negative side. I recently picked up some sale items from Sears, which were made in China Craftsman sets. I have here:
1. 999941 - Socket Wrench Set
2. 930024 - Socket Accessory Set
Those two items compliment each other and contain bit sockets like hex, torx, eTorx and an assortment of extensions and a ratchet.
Upon opening these items, I noticed straight away that the oxide finishes on the bits were dry, bone dry. There was even some discoloring and a dusty surface rust in small amounts here and there. A wipe down with some ATF quickly fixed this issue, but it is worth noting that the items were not oiled in the container.... the kits come in blow molded cases. Additionally, all of the non wobble extensions and universal joints in both kits had/have retaining ball issues (the ball that locks the socket in place). Most of them would not even insert into anything, socket or extension, at first. To remedy this, I again used some ATF and soaked the male ends (with the retaining ball) in the ATF for a bit, then exercised them with repeated insertions into a larger extension so I could have some grip.
Most everything is fine now. I would consider all of the bits with no issue, but I still consider the extensions to be of a poor quality, compared to the USA Craftsman and other extensions I have (both USA and Asian). Insertion still feels off, like it is out of tolerance or simply just not fitting and engaging as it is supposed to.
Just wanted to share as presenting all good and bad only helps in a real answer to the question I posed here.
EDIT: Some additional points I can make. The universal joints are serviceable. Meaning that there is a screw that can be removed at each of the joints vs just a pin. I do not recall id prior ones were like that, but some believe this is a good feature to have... me being one as you can disassemble to tighten back up and put back together when they loosen from use. None of the bit sockets are serviceable, but Craftsman never has done this except for their large sizes, like the T55 and T60 if my memory serves me right. All of the bit ends appear to be S2 steel, at least those that are marked. None are marked otherwise.
The drive end of the bit sockets have a good tight fit on a ratchet and extension. To test this, I used a Made in USA ratchet (Craftsman 3/8-Inch Drive Thin Profile Ratchet, 9-44995), a Tekton 3/8 breaker bar #SBH00118 and finally 2 standard and 2 wobble China Craftsman extensions that came in the kits. I felt this ok as it uses a USA and China Craftsman as well as a non-Craftsman breaker. The wobble extensions all seem to fit and function without issue, but I will say that all of the extensions and universal joints are not up to par. I am using a China made unbranded extension I ordered on eBay for like $1 for this comparison. Honestly, it has a better fit than the extensions in these kits.
The final 2 pieces are the 3/8-1/4 adapter and the ratchet. The adapter is junk. The retention ball is inset way too far and does not move much at all. It feels strange in my hand, so when I call Craftsman to get it replaced and they do not want it, I might cut it in half and have a look at the metal in there. It almost seems like where I scratched it trying to loosen the ball there is a hint of a copper coloring. Strange. Lastly the ratchet, well, it is a Craftsman ratchet. They never have been so good on the RP base models. This one is full polish and seems to be a bit longer and have a few more teeth. I counted 46 teeth, but that seems odd, but that is the count of clicks in a cull rotation. The reverse level is real stiff and somewhat bulky, but it does have a nice feel and works with no issues, skips or reverse problems.
With the cost paid being about 75 US cents per piece (averaging both sets and all pieces equally), I believe it is a good buy, especially if you need the bit sockets. If I were to throw away all but the bit sockets, I am still at a savings of at least 75% off of buying them in their individual metric/SAE kits... and luckily the bit sockets appear to be the best items in the kits quality wise.
