I find that Harbor Freight tools lend themselves to being ground down, bent, welded to and otherwise modified. I would not want to do any of those things to my pre-Wal-Mart Craftsman, Snap-On or other quality tools. HF hex drivers seem to be pretty good quality and fit, and the 3 torque wrenches I got from them have stayed in calibration for years. I have a long-pattern 15mm combination wrench which fits pedal flats well, no grinding needed
