Put it on today and it ran pretty well. All nuts were packed in small bags. None of them have scratches. During installation they went pretty clean. The tool worked fine. I think some of the problems people have had with tools wearing out or nuts wearing out are due to over tightening. Be sure to tighten to the specified torque, which is approximately 70-80 ft.lbs for a 12 x 1.5 thread. This is very easy if you don't have a torque wrench. Invest in one. Keep the tool semi-clean and wipe it during installation to avoid scratching it. On the top of my tool this only happened because I used a 12 point head that didn't fit properly to begin with, but the part that goes into the lug nuts came out pretty clean. It didn't scratch the paint. Very small outer diameter of the nuts, which is very nice.
