I was pleasantly surprised by how quickly I received my order. The instructions were straightforward, and the product performs even better than I had expected.
    Lee Verified Customer2024/06/01
    I now get excellent transmission on 4 bars, in place of the previously flaky on-and-off 1 bar. So I'm a very happy customer!
      Dagmar Berge Verified Customer2024/05/25
      This repeater works as it promises to do. Considering the performance and coverage, it is the best on the market.
        Tyreek Dare Verified Customer2024/05/20
        Product does work. Our house has a metal roof and surrounded by tall trees. WE HAVE SPARK AND WE HAVE HAD NO ISSUES!
          Norwood Rohan Verified Customer2024/05/12
          I inspect pipelines and have to be reachable by phone 24/7. Other boosters have disappointed me before, so I was sceptical of buying this particular one. I went ahead nevertheless and OMG! It gives 3 or 4 bars of signal in previously 1-2 sbars service zones.
