I got a "Great Neck" set and they have been really good. Apparently they are designed to break or burr over so you don't snap off the screw in its hole. Some do look a bit burred now. I think it was Hand Tool House (a shop in Frankton, Hamilton).
I put them in the F.A.T wrench. Which comes with a very limited range of imperial bits. I find the FAT very clunky with no feel and
I'm not that confident the tightness is really the same every time. but being an amateur, it lets me tighten screws without too much danger of breaking stuff.
