    This booster makes my phone signal from 1 to 2 dots and only in 2m distance. If you move 3m or more away there is no improvement at all. Same with flour, if its on second flour, at 1 flour you not having any improvements

    No more missed calls or late texts

    I used to always be told that I received text messages late and I'd always have a slew of missed calls, not any more thanks to this product

    Perfectly described

    This item was exactly as it is described on the site, cannot fault it at all Gone from 2 bars to 4 or 5 depending on which room I'm in.

    No lost calls no lost signal

    For the past few months since I moved into a new flat I haven't been able to use my phone without difficulty in any of the rooms. My sister recommended I try a booster and so I gave it a go. Now I don't drop calls or lose signal any more.

    Worth a go

    Signal here is very hit and miss. I thought I'd try this and boy does it work. We have 5 bars and excellent reception on all phones now, even better than landline. Simple to register and set up, takes about 1 minute to come online from being off.

    Good for rural areas

    Rural areas like the town I live in are terrible for signal. This booster changes that and allows me to get at least 3 bars of signal consistently

    In an emergency

    This product is a must have for someone like me with limited mobility. As I have a medical condition I have my phone with me at all times and I was worried that I might fall and be unable to get to an area with a good enough signal to call for help. Now I am reassured that should the worst happen I'll be able to contact someone at any time.

    Phone's working again!

    Since I switched to the O2 network for a cheaper contract I haven't been able to use my phone at home at all. I tried one of these boosters as a last resort and it's helped a bit. I can get all my calls now, although they're not all crystal clear.

    Setting up this signal booster took a little longer than I expected, not too much of an issue though because it now works very well
