Hi Mikael,
I unpacked the CETs and had the red one by my desk in the office. After some time I felt like my blood was racing through my vains. So much so that I checked my out-stretched arm to see how much my hand and fingers were shaking. Not as much as a tremor and after a while the feeling left me altogether. I now have them in my house and the feeling has not returned. Just an observation.
If you have heard of other people having such an experience I would like to know.
The journey has begun and I cannot wait to do some of my own checking.
Peter
