You bring up something that often gets confusing for those who have a little more education than many others.
In the marketplace, there is a concept referred to as, "Genericide". Basically, Genericide is when one comes up with a product, or process, that becomes so popular that the name of your product becomes so well known as to be the in the public mind as the noun, verb, and adjective of that particular thing. For example, people use the term Kool-aide for any non-carbonated chemical & sugar drink, and web searching information is said to be "Googling" someone, or something.
Scientifically speaking, electrolysis is an electro-chemical reaction. Original Galvanic electrolysis perfectly qualifies under this term, as does blend, because, when done to specs, the thermolysis is only a catalyst. When Thermolysis/Diathermy came along, it was marketed as "Electrolysis" because the public came to accept the idea that Electrolysis = Permanent Hair Removal. Since the general public did not understand the scientific basis for the name as process.
This lead to legal challenges to force so-called "Thermologists and Diathermists" to be barred from using the term "Electrolysis" and any derivatives based on the fact that their treatment does not conform to the chemical definition of Electrolysis, although it was, in fact hair removal.
In both the US and England, it was decided that since the average street level person would be confused if one said one was going to perform electrolysis on a dirty penny to clean it, and would scratch their head and ask, "How can you remove hair from a penny?", Thermolysis is allowed to be called Electrolysis, as it pertains to hair removal.
It only confuses those who know enough to know EXACTLY what true electrolysis really is.
Getting back to the Vector/Global/Any other scam machine, as long as an actual metal probe is inserted into the skin, the machine has the possibility to work. Some need modification, most are poorly made, and won't last long even if you do modify them, and it looks like the majority of them won't work if used as directed by the manufacturer. The Super Phaser Gold instructs consumers to apply conductive pads to their skin, and send electric charge into the skin and hope that enough chemical reaction takes place to cause permanent hair removal, WITHOUT burning off the top layer of skin in the process. If you don't know, that is not possible.
I hope this helps.
