"I really would buy this product again and again. A literal lifesaver for anyone in a poor signal area ... It truly is a great piece of technology."– Harry, FlareDB+ Customer

“I live in an old house that started out life with wood siding. Over the years it has taken on many exteriors including stucco and most recently metal siding and roof over all of it. Needless to say cell signal doesn't penerate much. This booster gives me full bars in most of the house. It is amazing not to have to do the 'where can I get signal' dance. Thanks so much!"– Shannon, FlareDB+ Customer
