An absolute must for every type of cell phone, mobile phone or portable phone (yes the one you have at home or in the office!) and every laptop computer. Stops that burning forehead and nauseous feeling while engaged on the phone or even when the phone is in your pocket. Prevents damaged DNA from direct signals to your phone or laptop. Can be easily tested by muscle or pulse testing to show that the phone it is not putting your body under stress. Don\'t wait any longer!
