Emilio R Verified Customer2023/12/04
This unit performs exceptionally well, providing a consistent 5 bars of signal about 90% of the time. Occasionally, it may drop to 4 bars, but we've been informed that this can occur when external signal conditions worsen due to weather. Anyways, we have a good signal at all times!
    Noe Daniel Verified Customer2023/10/31
    Since we bought the unit for our office, the staff no longer have to receive calls in the reception area they can do it at their desks. The price was a bit intimidating, but no regrets so far.
      Paul M. Verified Customer2023/10/31
      The product is fabulous, has an awesome UI, delivers a strong signal, is simple to install. It might be a bit too costly but from my past experience with signal boosters, this one is the best as it gives me the peace of mind I need.
        Mauricio Schultz Verified Customer2023/10/07
        Y'all need to know that on both frequencies my booster kit worked just fine. Perfect with an extremely wide spectrum in all aspects.. All in all, feel happy with the buy.
          Dee Stanton Verified Customer2023/10/01
          Ever since we installed this unit, our internet service has improved significantly, and, for the first time, we can use our mobile phones inside the house. We're very grateful for this amazing product.
