I bought 2 of these antenna's. I gave one to a friend and kept one for my self. Me and my Friend both put then on a Window to help with reception. I use a Motorola Q and my Friend has an I Phone both of us has service though Verizon. We went from either no service or 1 bar of service to 2 to 3 bars. I also have a Virgin Mobile MI FI Internet Data Card and it helped to increase my service from either no bar or 1 bar or service to 2 to 3 bars or service. Both of us live i rural area's. I would highly recommend this antenna to any one who has problems with cell reception. It also helps with Cordless Phones (if using the phone outside and Home Wireless(WI FI) network if using a lop top outside. You could use it on your car or a window at home.
