I bought this booster for my home office. For some reason the cell service at my house has gone from great to intermittent over the past year. I can actually watch the "bars" on my smart phone go from zero to 4 bars and back down again over a few minute span. Repeated calls to Verizon were of no help, same issue with multiple phones, etc... I was at the point of either going with a land line or a VOIP phone, as I need to be able to receive and place calls from my home at will, not while standing on one foot on the edge of the porch outside.
