Has anyone used one of these devices? They're not that cheap though.
It was recommended by one of the users in this forum years ago so had to dig it up. After doing some research on utube on magnetic pulsing, there's a lot of good these devices can do in killing of organisms/bacteria at a certain wavelength.
I did try colloidal silver years ago and it made me sick. Some claimed that it reduced their odor. Perhaps i didnt have the right one to start with.
