I would choose another option for this product. There is, what I’m assuming is an on/off switch but it is not marked. I hear nothing, feel no vibration, nor do I see any lights come on when the switch is in either position. It come with a screw driver for some strange reason, and a charger cord. No instructions of any kind. I have no idea if the product itself is in working condition. I was excited to get this device, but the experience so far is disappointing and confusing. I would recommend Amazon require more of the seller to avoid a very high percentage of these devices being returned

Why doesn’t this thing have instructions? I charged…finally got a green light to come but in only stays on for about 5 mins and shuts off. No clue if this thing is working. Does it make any sound? This is so bizarre. Sending back for refund.

This product really helps with dreamwork and sleep. It must be fully charged to actually work. I have it under my pillow and I've noticed that my sleep is deeper and more full. My dreams are clearer and more relevant to my day. There is no air coming from it or tone that you can hear so you might not think that it works. It seems to work as a constant emitter that does it's thing over the course of an hour or more. Also, it is smaller than it appears to be in the picture.

I have 3 other Schumann generators and have experienced good results so I wanted a small rechargeable unit to keep on my person. Very small, sturdy and the charge lasts for days! I keep this one on the night stand next to me when home with the other AC based unit on the table on the other side of the bed. I sleep in between the two and has helped me sleep more soundly, I'm a terrible sleeper so anything that will help.

Five minutes after I wrote this review the Blue light came on! Let’s see what happens. Is this perhaps a lack of instructions issue?Purchased March 2. Have been trying to charge it for three days now and it won’t charge. Tried different connections and it doesn’t work.Oh well. It’s past the return date.It should have lasted longer than two months.

This Wave Generator was helpful for the 3-4 months that I could use it. After that, the on off switch broke off. I could still switch it with a tool until the inner switch mechanizm broke! I now have generator that is perfectly good except I can no longer turn it on or off!

Why would a device come with a screw driver and no directions? An explanation would be helpful and then maybe I will change the rating to 5 star. Thanks

ARRIVED WHEN PROMISED, WELL-PACKAGED. NO INSTRUCTIONS BUT NONE NEEDED. THIS ITEM IS HELPING 97 YR OLD MOM SLEEP BETTER WHEN PLACED ~4 FEET AWAY FROM HER BED. I'VE ALSO ORDERED A COUPLE OF THE CHEAPER VERSIONS FOR COMPARISON AND WILL TRY TO REMEMBER TO UPDATE THIS REVIEW AFTER TRYING THEM, BUT EVEN AT $30 FOR THIS ONE IT IS GREAT!Updated on 8-16-20: The el cheapo vrsions I ordered from another vendor have no internal batteries so always require a USB port to operate. They are both still running but this $30 battery-powered version is far superior to them in every way. Still worth the $30 and still gets 5 stars.
