This product works like a gem, I was struggling with 1-2 stars in my basement. Now I get a consistent 3-5 stars! My only negative is any (and I mean any) obstruction (tv, wall unit, dresser, etc) will weaken the signal. So you want to place the inside antenna in an area that you frequently use the phone, other than that it works as advertised!!! Clear as a bell and never have to ask...can you hear me anymore!!!
