The two pieces are ok for the money. Hell the one pieces are good for the money but you do not buy them for the set you buy them if you need a one piece disposatool. They are USA made and I would rather buy them than HF. A lot of people will never use Torx more than a few times and if that is what you are doing they are fine. If you are looking for a forever set go for something else (but really any Torx bits are going to go bad at some point if you use them much)
I have had the craftsman, lisle, snap on, sk and other industrial brands fyi. Only broken ones I have are lisle one pieces. (edit, i have had broken snap ons as the bit itself started to fall apart, but the lisle ones snapped in half, also the SK ones I have and the craftsman ones have gotten loose over the years)
