I have one of these meters and recommended it in an earlier post.
Many people, including family, friends and others, prefer to remain oblivious to what phones and WiFi are actually radiating. When they see the red alarm band on the meter light up – and hear the screechy sound -many get the message immediately. We have to see it to believe it!
I know that several readers have purchased the excellent Cornet Meter. You will get more out of the meter from watching this excellent 15 minute guide video from well-known EMF Educator and Researcher Josh del Sol.
If you don’t have a meter then Josh’s video may well convince you …
