7.83HZ Schumann Wave Ultra-Low Frequency Pulse Generator & Audio Resonator, DC

Have had one of the cheap 5v ones from Alliexpress under the bed for six weeks. Tried it last year, but couldn’t sleep.

This time round I persevered, and it is easier. Waking up less, but no real idea if it has an effect. I have noticed that I am not tired during the day, no matter how many hours I've slept.

However, when I first started using them, I swear I noticed an improvement. New tweak bias perhaps? That's possible. My thoughts:

When first used one last year:
"I swear I hear a difference. A little more depth?
Tried on a bunch of different music.
Hard to pinpoint what the difference is."
A month later
"More authority to the music; a tighter grip. A little more depth as well."
Did notice more authority when I first used them. Has now blended in as the norm. I initially felt a little spaced out.

One thing I did notice was the two I had in my classroom.
One from Ebay, one from Alliexpress.

I have a pretty tough bunch, some with major social and emotional needs. 

My class was a calm class. I'm putting some weight on the Schumann Resonators. Enough to buy a third one for the start of the year.

You will very quickly hear both opinions. Of value, or not.

I have a few Schumann Resonators. My latest have been from eBay.
Two in the lounge (with speakers), one in the bedroom, and two in my classroom.

Their effect is sometimes difficult to pinpoint and the science is easy to pull apart, which makes them a target for criticism.

I bought on on advice from an acquaintance.
Is it BS? Placebo? I’m not likely to believe it but I can say it affects my daughter. I don’t feel any different with it on or off so maybe some people are sensitive to it.

I'm not totally convinced on it's affect musically; it's very difficult to measure, and I'm not good at A/B tests. 
However, I teach in one of the poorest suburbs of the country. Ever year I get many of the tricky kids, especially the boys. And this year, they calmed down. At the end of the year, a completely different way of behaving. This coincides being the first year with two Schumann Resonators in the class.
Luckily I only have 12 of these tricky kids next year ( I keep six from this year, but they are no longer a problem). With a third resonator (in a 73m2 room), I'm sure to be saying the same thing at the end of the year. It does calm people.

No telling what these children do when they escape the influence of the resonators.

How dare you judge my students from your elitist platform.
