I did some comparison shopping. Couldn't test other cell phone signal boosters, but this was in the right price range to do what I needed. Read complaints about it not working for people and other reviews stressing that it has to be installed correctly. Without this booster, my signal alternated between 0 and 2 bars, and that in only a few spots. With the booster it is 2 throughout the house and 3 or 4 bars closer to the booster.Could be better, but I'm satisfied.
