From 3 bars to 5 bars real quick. My small hotel finally has strong signal thanks to this device. I have to say I am delighted with this purchase.

    Benjamin Humphries Verified Customer2023/02/19

    Quick shipping and a good overall experience on my purchase. Only thing I would change is I would like to see a little more details on the parts and maybe a couple more pics. You can never have too much info. No issues with the device

      Merill M. Verified Customer2023/02/14

      Great product right there. Not only is the installation easy but it also comes with good instructions on how to operate and maintain it.

        Brad B. Verified Customer2023/02/12

        This solved a lot of problems in the house. We couldn't have more than one person using the network without losing connection. After installing this unit we all get to use our phones, and someone could be streaming their favorite videos without hearing any complaints with coverage. Now we wait till winter to see if the weather could affect things or not.

          Usually, I don't write reviews to products I purchase but this one I had to. I live a few miles away from the city, and cell signal is not very strong. Although we have a decent reception of 2-3 bars outside, in the house it fluctuates to one or no signal at all. I bought this signal booster, and after installation, I now get up to 5 bars in the entire house.
