    Consistency at last

    Finally I have consistency! I couldn't understand how one or two of the rooms in my house had a great signal and others had virtually none, but I don't need to even think about it now that I've got this booster. I've finally got consistency throughout the house!

    Works great! Can use cell phone again after putting metal .

    Works great! Can use a cell phone again after putting a metal roof on house. Metal roof completely killed my cellphone before getting this & hooking it up. Had it for over a year now I think & still going well.

    Better hotspot

    With my poor home broadband service, I'm heavily reliant on my mobile as a hotspot so I can work online. This booster has made that service even more reliable so I don’t miss out on valuable work time.

    Office dilemma resolved

    Although I could get a signal on my phone in our office, a couple of the other staff on the Vodafone network couldn't. I saw this booster was supposed to work especially well for the Vodafone network so I got one. It has made it easier for them to use their phones in the office.
