SORRY SOLD ALREADY
"a Schumann generator that emits a 7.83Hz electromagnetic field similar to the Acoustic Revive RR-77 - except that mine has five different power levels for dealing with different levels of electromagnetic pollution in the local environment"
I've had this for about a year and it is in perfect condition. I have three of these which is a bit overkill, so I am selling one.
Retails for $230 USD, asking $100
