Caution: I bought one of the above style balancers (though not that specific brand).
There was considerable play between the bore ID in the cones and the shaft OD. This ensures the wheel ends up slightly off-centre and therefore even a perfectly balanced wheel will have an apparent heavy spot. The shaft was not perfectly straight, ensuring that results were not repeatable.
It was more accurate to use the bike's axle resting on two jack stands, despite the higher stiction of the wheel bearings & seals vs external bearings.
I replaced the provided shaft with a piece of ground drill rod of slighly larger diameter and re-bored the cones to a .002" sliding fit. Now it works properly.
One final note, however: give the bearings and shaft a wipe before use. Any dirt there will also affect results.
