You can count on this booster for a reliable mobile signal. It has made my experience with mobile phones more pleasant because it ended call drops and improved sound clarity.
    Bernard Bartell Verified Customer2024/01/27
    I have not been able to install it for some reason... there is something I am not just getting right with the rooftop outdoor antenna positioning thing. However, I am just thankful about how great your customer service has been in trying to guide me through the installation. I am having someone come over and help me install it. I hope it can finally work fine and I can finally get around my signal problems.

      I purchased this booster kit for my office and so far, it does a perfect job. Every colleague of mine has noted an improvement in cell connection quality. They all love the product.

        There are many reasons which make this my best purchase of the year, one being, I have been struggling with the weak signal in my house for whole years and I have finally gotten rid of that problem courtesy of this incomparable signal booster. Second, I don't experience the annoying dropped calls anymore. Third, the customer care team were such darlings. Fourth, it was installed in such a short time. I could go on forever, it is a purchase I will just never regret.
          Rasheed Boyle Verified Customer2023/12/27
          This unit increased my signal to around 5 bars. To make it even better, it DOES NOT HEAT UP when connected to a variety of devices.
