Buy One for Each Person…NOW!!!
Why did you pick this product vs others?: The Natural Harmonic Rhythm of the Earth, is being Hijacked by the fake cell towers. I know those towers are not built for the reason they say, because they’re giving off Extremely Dangerous Electromagnetic Radiation and X-ray Radiation!!! 500 Meters is the minimum safe distance! These may help to reduce the impact on your body and health…. So, they’re worth the price! Buy one, and put them next to EACH bed. They are not amplified enough to cover more than 15-20 Square feet around themselves. Good Luck 🍀

Functional function generator but it broke down in less than 2 months
Bought it in January of 2026 and it stopped working in less than 2 months, power connection was acting up at first, and now it doesn't power up at all. Too bad, because I liked what Schumann resonance did to my sleep, I need to sleep less and was still getting a good rest. If vendor reads this comment, please send me a replacement and I will mention this in my update.

A surprisingly helpful tool
Take a moment to interpret how this works. Then try attaching it to some well made orgonite, check out electroherbalism dot com to find particular frequencies for particular discomforts, and feel the magic happen. Try attaching the alligator clips directly to your earthing mat and you can sleep with comforting wavelengths...just he careful to find the proper ones, for there are harmful frequencies out there for sure and you can either heal or harm yourself very easily with this. Hope this review stays around.

Warning
Warning, this item does not come with a power supply and is useless without one. If something is required to have an item to work, it should be included, chinese crap. Calls for a dc4-9v supply DC5 volt recommended.

Freq’y.
While it’s easy to adjust the offset and amplitude, it’s not easy to adjust the frequency while the output is active. Excellent variety of waveforms.
