Delta Shield for Cell Phones

  So I was reading about this Delta Shield in the news the other day.  Supposedly, cellphones emit harmful EMF radiation that can cause cancer and otherwise.  That I have heard often enough, but the article here claims that the Delta Shield, a small sticker placed on the back of the phone, can reduce harmful EMF by 93%.

  Makes me wonder what would have to be in that sticker to cause such an effect and whether or not it would mess with your cell phone connection (otherwise, most phones would already have this sticker attached no?).  I’ve tried looking this product up on several sites already.  Google doesn’t bring up any reviews or information other than the main site and some duplicate news articles.

  Has anyone actually tried this item before? Scam yes, no?
