    Great for technically minded

    I'm the first to admit that I'm rubbish with technology. I didn't have a clue when I looked at the installation guide. Thank god for my friend who helped me out. He had no problems.

    A useful home business tool

    If you're setting up your own home business and want to be sure that you can be easily contacted by clients I'd recommend one of these boosters. It's given me confidence that all business calls will come through.

    This one works

    This is the second mobile signal repeater that I've owned. The first (from another company) broke after a couple of months so I replaced it with this one. Already I can see that it's better made and offers a better level of service.

    Free delivery - streets ahead of the competition

    One of the main reasons I chose this product was because of the free delivery in the UK offer. Nobody else offered the same level of value.

    Signal less strong in some areas

    Although this does work all round the house, it's definitely a lot stronger in some locations than in others.
