Review on Circuit Performance 7-Point Star Spline Lug Nut Key Tool in Black by Brad King

Cracks if tabs are overtightened. Had no trouble installing and removing, they have been tightened to 80lbf dozens of times. After being beaten at the tire shop, the tool broke when I tried to take them off. It was very difficult to remove the tabs afterwards, so I know the star tabs are effective as locking tabs. The tool needs to be redesigned to be thicker. Just ordered a new set of grommets, will buy another tool and tape it over it so it doesn't tear again in the future. Keep your eyelets to spec and you'll be fine. In any case, using a percussion gun or excessive turk on aluminum nuts is stupid.
