Does it? All I can see on their site that implies blocking/jamming is "balance and harmonisation of the harmful effects of imbalanced electric radiation", which seems vague and pseudo-science-y enough to not break any laws.
Are "balance and harmonisation" exact enough terms that you can disprove them? Can that sentence even be called a technical or medical claim considering how vague it is?
Vitaminwater has some drink called "balance", would that fall under the same thing? They also have something called "revive" but I don't think you can call it illegal just because it won't revive people from death.
