Review by So CA Teacher

I bought this gadget to be able to detect and avoid wifi, as wifi gives me headaches, nausea and heart disturbances. I carry this in my purse and it is an easy way to figure out what the strength of the wifi signals are. […]nIf this item is not available there are others like it on Amazon, do a search on WiFi detectors, or a RF field meter can be obtained, such as an Electrosmog Meter.
