Initially bought for a large home surrounded by other large homes, I installed this unit to boost the signal while in half of this particular house. I often dropped calls prior to this in the various rooms of the house facing to the north side of the building. After installation I didn't drop a call at all. The product itself operates as designed and intended. However the issue arrises with the difficulty of installation. If you are using this, its likely you have a two story house. Therefore, you're headed to the roof to install the antenna portion if you expect to get good reception. I attempted to use this on an outside wall and got poor performance. Moving it to the roof made all the difference.
