Bests & Worsts Reviews from Amazon

A cage that reduces the signal strength of transmitted power will also reduce the strength of received power. This means that the signal transmitted by your phone, laptop, smart watch, fire stick, or other Wi-Fi device needs to be more powerful to penetrate the shield. Many people don't realize that the body absorbs thousands of times more radiation from the personal devices close to our bodies than from the routers, small cell sites, or towers that are much farther away. This is because wireless signals dissipate at the square of the distance they travel. Many also don't realize that wireless devices adapt their signal power internally according to the distance the signals have to go and the interference they encounter. Wireless devices measure received power and tell the device on the other end to turn it up or down until it gets into the optimal zone for high speed transmission and minimum battery drain. If you shield your router, it will tell your personal device to increase its transmitted power level. That causes your body to absorb more radiation. This device doesn't protect you from your phone. I suspect that the people who fear EMF energy aren't looking to increase their exposure, but that's what will happen if you use this thing. It's a scam, and a hilarious one at that. Maybe I should go 2 stars for the lulz.
