Works as advertised!!!! Very Pleased...Would suggest to any one in a rural area with a weak cell signal...

    Wilson P. Verified Customer2023/08/04

    What I loved about this product is its wide coverage range. You don't have to be constantly near it to get coverage. However, you have to get the installation right. I had a few troubles setting mine up, but once I figured it out, coverage has been superb.

      Greg D. Verified Customer2023/07/25

      We have gone from no phone signal to 4 to 5 bars in our house. This now means that we don't have to keep outside to try and make calls,

        Julian Picot Verified Customer2023/07/16

        Great. We'd never be able to have a signal in our building unless we stood by the window. But now, we have full bars of signal. Thank you

          Williams F. Verified Customer2023/07/10

          For years I struggled with coverage in my office. Every time I could barely get a bar of a network in my cell phone and communication was always a problem. I have to say this device is a life saver. Now, I have superb phone call quality, and my internet connection is as strong as it gets. I can send and receive emails anytime. Thumbs up!
