SYB Clip-on Phone Pouch to Shield Cell Phone EMF

Got this Clip on phone pouch for my dad for his birthday. I got this for his phone if he does not want to you use case he can use this instead. It is good for him since it is black and goes with anything. Got this free for and unbiased review.  http://www.amazon.com/dp/B019KWS9BA. #SYBPocketPouch.
