You think that a little piece of shiny plastic will increase your cell phone signal? Well, how about you glue a mineral rock onto the back of your phone? Or maybe wrap it in foil? Seriously, you think that if a 1c solution to the cell signal problem was available, wouldn't your cell carrier give it to you for free? As much as you want it to work, I have bad news for you: it won't. If you have signal issues you need to spend real money, $$$, for a reputable booster like Wilson or zBoost or Uniden (all available at Amazon). So don't get it, because if you do, you will feel really stupid that you fell for it.
