    Need to get the antenna in the right spot

    I didn't realise how difficult it was going to be to get the antenna in just the right spot. It's definitely a two man job.

    Very happy with my purchase

    I just want to say that I'm pleased with my purchase. It's great value and it lets me get more out of my mobile contract.

    It's so refreshing to be able to use my phone indoors

    For the last couple of years since I switched to O2 I hadn't been able to make or receive any calls at all from inside my house, only from the drive or the back yard. I wasn't sure that this booster would help because the signal was so bad but it made just enough difference to mean that I don't have to put my coat on and head outside every time I want to use my mobile.

    No more sitting on the steps!

    I didn't mind sitting on my garden steps to make phone calls during the summer, but once the winter came I really wasn't enjoying the experience. This booster has allowed me to sit indoors and make calls.

    So happy!

    I am so happy with my purchase of this signal booster, it really speeds up my phone overall when I'm streaming music and videos. I'm in danger of becoming addicted to YouTube now!

    Does exactly what it says it does.

    I was about ready to change cell phone providers when I was told about a cell phone booster. Although the cost was a little steep I made the purchase. It was very easy to install and the effects were immediately noticed. This is a great product. No more dropped calls inside my home. Thank you, Mobile Signal Boosters.

    Great product worth the cost!

    Went from no bars at home to a minimum of three. Can now actually use my cell at home. Works on clear or cloudy rainy days, Glad I found this solution. My cell provider is Vodafone...
