Adjustable Schumann Resonance Generator (0.01Hz-20kHz) | Healing Frequency Generator, Rife Machine, 7.83Hz Sleep Aid, Stress Relief, Relaxation, Meditation & Yoga Enhancer, USB Powered

These devices are amazing. I have struggled with insomnia for over 20 years. It's helping me get some sleep. I also had a concussion. When I started using it, my symptoms started to disappear. I set it to the pain relief frequency and my coworker (who had had shoulder pain for months) noticed his pain ease. I bought 2 more. Now I have one for my car, home, and work.

I was very surprised by the quality of this Schumann generator. It is easy to use, feels well built and works perfectly. Since I started using it, I notice a more relaxing and pleasant atmosphere. In addition, the frequency adjustment is very practical.

Faulty. So far I've not managed to make contact with the seller - Still no contact with the seller. Going to send it back! Rubbish product. Rubbish service.

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.
