Link works fine for me.
I've got a similar tool under the Goodyear brand that I picked up at PepBoys a few years for half that price. Works like a charm when I'm rotating tires, etc. Used to use it at the strip to mount up my DRs on my other car while waiting in line for the place to open. Very handy, no doubt about it.
BTW, I would still hand torque the lugnuts when installing though.
