Review on POINT SPLINE TUNER Mr Lugnut by Juan Castillo

Total nonsense. I thought the other review saying he split it apart was an anomaly. nope; On the first wheel, the case deformed and split about 0.75 inches on the sides. These wheels were hand tightened just a few days ago at the SCNAX autocross, so that doesn't mean the lugs were tightened with air tools or anything, just tightened with a serial wrench. I bought two. I used the second to reinstall the wheel because who knows if it will fail on wheel number two. Unfortunately Konig Feathers have very small ledge wells so you MUST use a skinny wall socket. I used it this weekend and it worked great on all 4 wheels.
