    Working from home

    I've been working from home for the last year, but before I installed this booster I was having to operate out of the local coffee shop because of the appalling signal in my home office. Now I've got this booster I can actually work from home again - and it's saved me a fortune on coffee!

    No more problems - thanks!

    I spent two days trying to set this up before my wife forced me to call the helpline. I wish I'd called sooner.Turned out I'd been doing it all wrong but luckily the staff were so knowledgeable and helpful. They talked met through everything I had to do so I could get the booster working instead of being an expensive decorative item on the shelf!]

    I can't manage without a phone - it's literally my lifeline so I had to find a solution for my new flat. After doing a bit of research I came up with this product and thought I'd give it a go. I won't lie, it wasn't the easiest to install but now I can chat to my mates and use the internet whenever I like.

    Better with the Yagi Antenna

    I first bought this without the Yagi Antenna and didn't see much of an improvement. When I called the helpline the advisor recommended that I try the Yagi Antenna and if there was no improvement I could get my money back. I'm glad I decided to try it because now it works like a dream!

    a 2 bar boost

    Although two bars was enough signal for me to receive calls at home, it wasn't really enough for me to hear clearly and I was always worried about misunderstanding clients. Since I got this product I can hear properly again which is great since I'm expanding my business.

    No dead areas

    There are no longer any dead areas in my house, which is wonderful. Before, I couldn't use my phone in the kitchen, the study or the dining room. This signal booster has solved this problem perfectly.

    Much stronger signal

    I can finally take calls from the sofa rather than having to ask callers to hold while I wander up and down stairs looking for a stronger signal!

    4G - unheard of!

    I'd been despairing of ever getting a 4G signal in my living room. In fact, I was lucky to get an E symbol. As a last ditch effort I got this booster and I just couldn't believe it when I fired it up and got 4G straight away. Wow! Speedy loading - something I never thought would be possible!

    No more leaning out the window

    I used to have to actually practically hang out of my window to make a phone call, but now I can go anywhere I want in the apartment when I make my calls.

    Could be better

    When we purchased this we thought it would be 5 bars all the time but after going through all the trouble of meticulously following the directions and installing this, we might get 4 bars at any point and not always that much. A little disappointed for the amount we spent on it but hey, at least we get phone calls now where before it acted like we never got them even though the phones would show missed calls and voicemails.

    Out of the Dead Zone

    Increased bar level from a 1 or none to 3-4, phones couldn't be used in certain parts of the house or in summer would lose it. This has made possible get service without having to stand in 1 corner of the house.

    A great way to improve 4G reception

    In my case I see a clear gain in reception even with the antenna being installed inside.It went from 2 bars without this antenna (-103 to -106 dBm) to a solid 3 bars up to 4 bars (-96 to -94 dBm) once the antenna is properly connected to my dongle.
