I was experiencing a very poor signal from my cottage but after I had installed the booster I was able to get full signal compared just to one bar before. I can now comfortably browse the internet and watch YouTube videos. Straightforward install and great performance.
    Connor Legros Verified Customer2023/09/23
    I have been following the instructions and now I can get 4 G connection inside my home. Everyone had to go outside before I installed this to get a cell signal.
      Conrad Senger Verified Customer2023/09/16
      I used to get zero to one bar when I was indoors. Talking from within the house used to be a major problem. On installing the product we are now able to receive up to three bars. We can now Netflix and use the internet at ease.

        The device works magic on your signal. If you don't believe it, just unplug it from the power source and see. When it's on, you're assured of a reliable cell phone signal. It's the opposite when it's off.
          Donnie Witting Verified Customer2023/09/12
          The booster is a real saviour. It ensures that I have a strong, stable signal indoors while improving audibility when making calls. Besides, it improves internet speeds.
