I think that the number of Earth Calm products I use has made all the difference. I started with the home system and sleep sanctuary (put right behind my head in the headboard) and found some relief. But it wasn't until I got the quantum boost and put it on my wi-fi machine and put another quantum boost on my Apple TV machine and put quantum cells on my laptop and phone that I got the full relief I wanted. I think all the layers of protection have made all the difference. My sleep had been irregular for some time and sleeping a full night without waking up feels like heaven. And waking up without a daily headache makes things even better. I venture to say that my body had been affected negatively by EMFs without my realizing it for a long time. THANK YOU for your products. I'm so grateful that they really work!
