As much as I wanted this product to work and effectively reduce RF interference, it failed miserably. The idea is good, but the execution is not so good. The product claims to block RF/EMF, but in fact it can actually increase exposure as the cellphone has to constantly "reach" for communication poles, greatly increasing the RF signal coming from the phone itself. I'll be posting a short video review shortly showing the objective, verifiable data I got from my HR meter. I just felt compelled to warn people, those who may not have a blood glucose meter, who use this product and believe they are protected. Last word, yes it can minimize direct exposure to the head while on the phone, it still puts out an unhealthy amount of radiation. It's best to turn off cell phones, WiFi, and Bluetooth until you need to connect. Using wired headphones is great for keeping your device away from your body.
