Cell Sensor soothe paranoia

The paranoid will definitely love the Cell Sensor EMF detector, as this device is capable of measuring electromagnetic fields and radio frequency radiation. I suppose most people are extremely concerned with both, since we now live in a world where wireless connection is pervasive. Do those unseen rays and radiation actually harm us in the long run? Will it cost us to bear offspring that have an extra arm or leg? Why not purchase some peace of mind with this $35 device instead and lay those ghosts to rest. I personally think this is bollocks – so what if you know the level of radio frequency radiation around you, what can you do about it? Move to an island and be a hermit?
