This really has helped my family out. It used to be that we had to step outside on the deck to talk on our phones, and place them next to a window to get them to pick up enough of a signal to even ring. Now, we have a good enough signal to talk throughout our mobile home. I usually received only one bar or no bars outside and frequently lost calls while sitting on my deck. We used to joke that the wind was blowing in the wrong direction. Verizon came out and determined that we live in a 'Marginal coverage area' and this was basically the best we could expect from them. I thought that I would give this product a try before I tore out my hair.
