We just relocated to a remote place where we initially had a single bar of 4G network or nothing at all. I bought the unit and installed it in less than an hour. When we located the spot with the strongest signal, we mounted an external aerial. We now have a reliable service. I strongly recommend the product!

    I do not have Wi-Fi in the house that I currently live in. So whenever I want to do something on my laptop I use my phone to tether. Slow internet speeds on my phone means little or no network on my laptop and that grates my poor nerves raw. I bought this unit to improve the internet quality and true to its word, my download speeds are very much faster. This bothered me for a long time I am glad its over.
      Stanley Brekke Verified Customer2023/11/02
      Purchasing this unit for our office has proven to be a wise decision. It seamlessly caters to the needs of all three of us, delivering exceptional speed across the board—calls, download speeds, and streaming. I can efficiently handle my emails, and the remarkable clarity of voice calls continues to impress me. I recommend it to anyone seeking relief from the frustration of dropped calls and sluggish internet.

        Perfect, works perfectly, good quality, durable. Easy to install and is a life saver when the wifi goes out.
          Clarissa Lemke Verified Customer2023/09/21
          All my life I have never had 4 bars on my phone, let alone 5. My parents house was very far from town and I had even gotten used to the 3 and below bars. I recently moved out to my own place and got a mobile signal booster as a present from my elder brother. That was so thoughtful because I do not live so far from my parents and the network problems abound. I am very very happy I have 5 bars. I am even planning to buy my parents a unit of their own now!
