Really happy with this! We live in the middle of 150 acres of pine trees, in a metal home with a metal roof. We had to go outside to make or receive calls. Since our landline kept getting cut by the road graders we had it turned off. So we were basically without any phone service at all unless we were outside and standing on one leg with our heads at a precise 33.5642 angle, and hoping we didn't need to make or take a call in the middle of one of Florida's famous lightning storms or when its freezing or 99 degrees outside. This booster cured that problem! Easy to install in less than an hour, and no more callers asking when I started stuttering and me having to explain I am outside and it's 30 degrees and my dang teeth are chattering!
