EarthPulse Sleep on Command BioMagnetic PEMF Device. Turns on and off and changes settings. Minor scuffs and scrapes from normal use. I don’t really know much about what this does or exactly how to use it. Comes with some instructions. I did see a few youtube videos and tested it the way I saw on youtube and it appears to operating. I HAVE A VIDEO SHOWING HOW I TESTED IT BASED ON WHAT I SAW ON YOUTUBE.
