I have owned this piece of property for over 13 years.  I have had less than mediocre cell service.  Dropped calls, missed calls, choppy reception TO SAY THE LEAST.  But with just one bar of service, you can boost your signal with this product to anywhere between 3-5 bars constantly.  This just may save my marriage (LOL).  I don't usually spend the time to leave reviews, but did in this case.  I would TOTALLY recommend this product.  It can take just a little bit of service, and turn it into a lot!!!
