Are cell phones dangerous to use? Why to take a chance if you have an easy access to something that can prevent the negative effects of harmful radiations coming from your phone. R2L is an anti-radiation chip that is scientifically-tested to substantially reduce radiations without interfering with your cell phone's signal. It works by converting RF (Radio Frequency) signal spikes into harmless bursts of energy, which means you are safe always. Just place it on the surface of your cell phone and prevent the penetration of harmful radiations by 70%. IF THE CHIP DOES NOT LIGHT UP, PLEASE MAKE NOTE OF THE FOLLOWING 3 POINTS: The light not lighting up means one of the following has occurred: -99% of time the light not lighting up is attributed to the R2L being in the wrong position. -You are too close to a cell phone tower. -Your Wi-Fi is not shut off. The R2L only works on the cellular signal not on Wi-Fi signal.
