    This device can do what EE can't!

    I've been with EE for years now, and have always struggled to use my mobile in my house unless I stand in the corner of the bedroom. Thanks to this booster I can now get a signal downstairs too.

    Value for money

    A great booster for its price. You just need to put the expernal antenna in the right place and everything will work properly.

    I can use my phone like I've never been able to before

    I'd got used to not being able to use my mobile in the house, but after my son bought me one of these I was amazed to unlock a whole new lease of life from my phone! Now I'm streaming from YouTube and Spotify every night when I can't sleep!

    Seen some improvement

    Won't say I'm 100% happy - still have a few dead spots but I've got more choice about where I can make calls now.

    No longer have to constantly call my voicemail

    I was getting really sick of being told that I had voicemail waiting every time I left the house. All my calls were being dropped because of the dodgy signal. Since I got the amplifier I don't have to constantly call my voicemail to catch up on messages as everyone can get through first time.

    Can hardly believe it!

    I'd given up all hope of being able to use my mobile indoors, but now I can!
