The round balls supplied are a joke...cheezy high-gloss industrial ball bearings. Spheres offer NO surface contact whatsoever (except for one "point" - remember geometry class?).
The case is cheezy...a plastic clarinet case.
Just order the magnet and a dozen of the stick-on pads
Order some convex dent balls from Ferree's...and get a 2" diameter X 4-1/2" long chunk of cylindrical steel from a metal supply place for the "handle".
Perhaps you can find a 2" diameter X 1/2" thick (wafer) "earth" magnet somewhere else, too, and then you would have the entire thing.

As to how it works...OK. It will scratch lacquer, and if you go over and over a spot - completely remove old lacquer from the friction.
Small deep dents in thick newer brass are semi-hopeless. The incredible video demo's you've seen are on old paper-thin instruments.
