For something I’m interested in, your topic was a must read in order to gain some insight on where to start and how to do so safely. Unfortunately, I’ve got no idea on the devices you’ve mentioned but what I do know now is that, they’ve got no spot in your personal space as, they could potentially be the source of certain radiations which could become dangerous to health.
No one wants to make money only to come off with health challenges right! So this is a topic worth noting and thanks for sharing.
