All Wilson products were excellent but not user friendly. Directions included did not explain products and their use properly. For example, the green light &#34;lit&#34; is not mandatory to use the amplifier. Also, as long as the &#34;no phone service &#34; icon is not illuminated on the phone, the amplifier will function. Again, the instructions are incomplete, especially concerning building installations. Please pass on to factory. I almost returned everything out of frustration but stuck with it. I had the antennae taped to a broom stick!!You probably have abnormally high rate of returns due to the above.
