I bought this item and was a little sceptical if it would work. I had 2 to 3 bars of signal on my cell phone if i got on the roof and anywhere from 1 bar to no signal in the house. The closest cell phone tower is 7 miles away. I bought this unit, installed it in a matter of minutes and was wonderfully suprised. I put the base unit in the living room and I have 5 to 6 bars of signal in the living room and 2 to 3 bars in all the bedrooms and 4 to 5 in the kitchen. It is a wonderful product and works great for our 1600 sq. foot home. Would highly recommend it
