    Bought wrong product

    I made the wrong choice when I bought this - it didn't have enough coverage for my house. My fault - I should have researched it better. The helpline was really helpful though and explained what I could do to solve the problem.

    Great stuff

    I was really hopeful that this product would help me to make calls without having to stand outside my front door. I can now get a signal in my porch, in my kitchen and in my front room, although I still have no decent signal in the back of the house.

    Don't struggle with no signal - get one of these!

    I wish I'd bought one of these sooner. It's taken all the work out of trying to find a signal!

    I'm a massive fan

    I am a massive fan of this product, it really makes a difference. My phone used to only get 2 bars of signal and now it gets 4 consistently

    It works great for me.

    5 bars in the basement. I've owned previous models of your company and I will never buy any other brand if I have a choice.
