The tool was fantastic. I used a washer underneath because there was only a tiny bit sticking out of the bolt, forcing me to pry it off with a screwdriver. I was afraid that I might damage the instrument but it is very durable. I don't remember reading that it has bearings and rotations. It's a handy tool and I'm missing another one to take with me when I'm off-road. I used it on a 2007 Jeep JK. The wheel studs were 1/2β-20. Worked better than a bunch of pucks. I highly recommend.
