This device has had lots of hard & beneficial use, lots of all night sessions.
Our family is continually astounded with the value, health-wise, which is packed into this small device. As we age, currently in our eighties, more and more we find ourselves sleeping with them applied to locations of chronic discomfort. We are getting cures that conventional medicine cannot explain. For instance acid reflux caused by a leaking LES (Lower Esophageal Sphincter) was corrected to complete normalcy in one session. That, of course, is truly fantastic.
