The first part of the above part numbers is the sticker company, not to be confused with actual sticker manufacturing companies. These are sticker sticker companies. Note: sticker sticking is also subcontracted. As far as I know ""Craftsman"" has always been a sticker sticker subcontracting kind of brand. Like most of the 80's-00's stuff was made by Ryobi (aka all Craftsman part numbers that start with 315.xxxx. IIRC the 113.xxxx stuff is most of what was "Made in the USA" and was the part number prefix for Emerson.
Venture capital is what it is. They are counting on consumer ignorance and resistance to change in order to market their overpriced junk. If that bugs you more than it does me, maybe you're motivated enough to beat them at their own game and seek out the best value products for you, forging your own path. For instance, when Sears sold Craftsman stuff made by Ryobi. Ryobi made better stuff at a better price under their own brand.
History repeats. Shinmax's house brand is Cutech:

Attached is my spreadsheet with test results for 17 total U2010B chips tested in and out of circuit. Maybe someone that knows more about silicon can comment about the range of values and anomalies. Is the range of resistance values seen here normal?
I am really surprised the chips labeled ALI-12 and ALI-14 worked. Chip 12 appears to have major issues with the sense pins and 14 has no connection on Csoft at all. Of the bad chips on sheet 2, my favorite is the one with no connection to the ground pin.
The spreadsheet was made with Libre Office, but also saved as an xlsx file for 'doz users, and/or there is a PDF.
