If you’ve been worried about your brain being fried by your cell phone, or your butt, if you keep it in your pocket, then worry no more. Pong has a line of cell phone covers that improve reception, while at the same time blocking cellular radiation.
According to their site:
Pong’s patented antenna technology redirects the potentially harmful electromagnetic radiation (EMR) away from the your head, which reduces your radiation exposure by up to 95% below the Federal Communications Commission (FCC) limit.
If you’re interested to know how it all works, read their testing and certification page, or watch the video they’ve posted on Youtube.
