Bio-Healing Frequency Generator

I am still trying it out. I enjoy using the earphones to experience various frequencies but I can't yet tell if I feel differently. I keep it on without the earphones overnight. I am old and I believe everything I am told. So, if it does reach my brain when I can't actually hear it, will be delighted. If I notice a difference.... I will let you know. I was a Hippie, so I tend to hope for the best in new ideas and ways of thinking.

Great product. I bought another before online with but protective case, no earphones, no speaker. Just the green board with Chinese symbols and the digital display of#'s i can't tell if it even worked. I took the chance that this would prove accurate. So far so good. Seems to work great

Sending an operator's book with it would have been nice. I didn't know there was a "start" button on it. Then I had to experiment to find which buttons were which. I haven't felt any changes so far, but I expect it will take some time before it's noticeable. Is there a time limit to keep it operating? I usually keep it running most of the day, and sometimes at night.
