I bought the signal booster based absolutely on reviews I read. I was a bit skeptic in the beginning. However, to my pleasant surprise, the installation process turned out to be relatively straightforward, even for someone like me who typically avoids DIY tasks. My phone signal had an immediate boost, it has been 4 to 5 bars strong. I hope it is not one of those things that start out strong then wane with time. If it remains this way, I am set for everything.

    My house is surrounded by dense vegetation. After installing the kit myself, my mobile phone signal went from weak to a steady 3 or 4 bars of 4G. No more delayed messages or dropped calls. Internet connectivity is now fast and reliable. —it's affordable, and the performance surpasses satellite Internet. Many thanks!

      Our home is in New Plymouth, a picturesque town 80 kilometers away from the nearest urban center. Our house sits 12 kilometers from the closest cell tower, and, regrettably, we've struggled with unreliable connectivity. We were initially skeptical about this solution, but it has pleasantly surprised us. I wholeheartedly recommend it!

        We live in a low area region most likely the absolute bottom of the Mountains with no cellular reception. I bought this phone signal amplifier for my house. I pursued the configuration and setup guidelines and was amazed when I got a 4G network and 3 bars for cell service. I hardly could believe that all the gadgets I use for my business had a signal and that I could make and get calls. I am no longer disconnected and I can associate with the rest of the world. Much obliged to you for this marvel item. I Like it.

          The signal for the office was really bad and we could not answer calls well or receive and reply to mails the right way. I am so glad I bought this unit for the office. The tough times of dropped calls, delayed emails and the frantic search for signal are gone. This could very well be my best purchase in a long time. If you have a problem with weak signals you should totally get it. You will not regret it.
