I took my time to test the OHRB and it was unclear in between. Does it work now or not, or do you want it to work? Do not be a naturopathic therapist for nothing. So it took a while until I now know for sure that the OHRB works. I have lent the device without thinking last Friday through Monday and I’m sure I will not do this again. What a change in the house when it is not plugged in and just like it is plugged in. We and our whole house are much more in harmony when the OHRB is inserted.
