Review on Insulating Reflective Emergency Blankets for Marathons: Stay Warm and Safe by Roy Ramos

Ever since I noticed that the EMF (electromagnetic field) around the circuit breaker box was off the charts, I started looking for a way to protect myself. After reading online that mylar is excellent at blocking electromagnetic fields, I decided to take these blankets and hang one of them in front of the CB box. It looks like a small golden curtain :-). Most importantly, it greatly reduced the EMF directed at my kitchen. I would highly recommend this to people who have this CB box in their bedroom - you won't believe how many people have it in their bedrooms. I also have one of the blankets for emergencies in the car. Great quality at a great price!
