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.
    Consuelo Jerde Verified Customer2023/11/15
    I live 2 km from the cell tower but since the house has thick walls and a metal roof, the signal is not strong enough. When I installed the unit, I was able to use my phone from within the house. I am delighted with its performance and the ease of installation.
      Wilburn Becker Verified Customer2023/10/27
      I bought this device last month and ever since problems with network coverage feel like a century ago. It's almost as if I don't remember what losing connection feels like. I would recommend this signal booster.... Although I don't know its durability because I haven't used it for a long time.
        Benedict Hartmann Verified Customer2023/10/05
        At first, I was a bit skeptical if this would work in my apartment since I'm surrounded by some huge buildings which always seem to block the signal. With this signal booster though, I never get anything short of 4 bars cell service. Its efficiency is amazing.
          ISRAEL O. Verified Customer2023/09/24
          I just can't believe after years of struggling with phone signal the solution was there all through. Now after purchasing this device, my phone signal is so strong that I clearly hear every phone call.
