No subastantiation whatever regarding the "electromagnetic" mentioned in it's title (Neodymium magnets are NOT elecromagnetic).

They do not state who granted the "intellectual patent", but note that this is different to a patent and again reeks of snake oil

Wording and phraseology is not normal English nor American and I would suspect a translation.

Have been completely unable to track down the manufacturer but it might be Shooting Technology in Italy.

I have no doubt that they kit does clean cases but IMO wet tumbling with stainless steel pins will work as well at a fraction of the price.
As far as I know they work like these
