Bests & Worsts Reviews from Amazon

I switched from a verizon cell phone to the iphone 4 and at&t. Coverage in my area, Sedona, AZ is not that good with at&t. In my house I was getting 1-2 bars and a few dropped calls with my new phone. When I went up on the roof, I discovered that I could get 5 bars on my phone. So I bought the Wilson unit and installed it as per their clear instructions, putting the antenna on the roof and the amplifier in my living room. It raised my bars in the house to 4-5 bars. Calls are clear and strong now. Very happy. Important point: what you need to understand is that this unit will only amplify an existing cell signal. It cannot amplify a non-existent signal. In other words, you have to find a place in your house, probably on the roof, where you get good strong cell reception. Then the unit will bring that strong signal into your house. The unit cannot create a signal where none exists.
