    I can talk clearly

    I can talk more clearly now on the phone, only few complaints on the other end of people not being able to hear me.

    Can take calls anywhere in the flat

    Ever since I moved in I've been losing the will to live with my inability to use my phone inside the flat. My stepdad bought me this and I think it might be the best thing he's ever bought me!

    Solution for houseshare

    I share a house with three other people. We're on two different networks and while my two friends could get a signal fine (they're with O2), me and my other friend on Vodafone always struggled until we got a booster. Now we've all got a proper signal which is great.

    Friendly customer service

    I had a whole world of issues trying to set this up, but thanks to the help of the customer service team everything got sorted out. I can't be complimentary enough about their friendly attitude and "can-do" approach.

    A workshop lifesaver

    When I'm down in my workshop (or the man cave as the wife likes to call it) I can't get her calls since there's no reception out there. I can't avoid her now since she installed this booster. My phone rings every time.

    Good upgrade

    I was pleased with the results from using this booster that I've upgraded my phone for the first time in years - I can finally get some use out of it, the only thing is doesn't catch signal everywhere in a house!
