It’s a scam for price. This thing is worth only 9 to 20 dollars. This supplier is overcharging people: I claimed a refund and the supplier left amazon.

I just came to my past orders to repurchase this thing...why because I put it in my son's room who is 10 and has been having difficulties falling asleep and also he wake sup early a.m and can't fall back asleep. I've tried everything, sleep doctor appt. Medication, weighted blanket, magnesium and melatonin, ect ...list goes on...I bought this frequency thing for myself but since the day I put it in my son's room...he falls asleep within an hour and when he wakes up at 3 or 4am he falls right back to sleep!!!!! SO he can keep it! I just spent another 70 bucks to get my own...this thing actually works...I'm so happy..it's been in his room for almost a month now and him having better sleep, his moods and personality are so much better.

Does exactly as it says. I plugged in headphones to test the frequency using my tuning forks. A perfect match. Does NOT require sound but you can add a speaker or headphones. The instructions were a little difficult to understand but I emailed the company twice and they responded very quickly and explained in detail what I needed to know. UPDATE : My brother lent me a pair of computer speakers as the device is not powerful enough for the resonance speaker I bought. The computer speakers have a volume button that can be shut off. Everything works perfectly now.

Does not come with any cover or case. And my biggest fear is that it will beak as it is all exposed

It's great for sleep and other medical. Research Royal Raymond Rife inventor.

The cords are wat too short. No instructions as what currency to use for what.
