I used to have one, dang I lost it. But are you also using a grounding mat or anything like that. I got one and I wasnt sure of it’s effectiveness until my cat that hides under the bed every day started laying on top of the bed on it !
#asknostr what's your preferred EMF detector? I've seen this one recommended and it seems good, but I like to see what other people say.

I have a grounding mat, and silver-threaded sheets on top of that. It's made a big difference in my quality of sleep! Right now I want to experiment with EMF leakage from outlets using copper outlet cover plates.
