    3G restored

    Before I got this, it was once in a blue moon that I'd get a 3G signal in my house. Now, it's there 24/7.

    Friendly advice

    When I used the live chat function to talk to an advisor about which size of booster to get for my small terraced house I was impressed by the quality of the advice and the helpful attitude.

    Best present ever

    My cousin gave me this product as an early birthday present and I've never been so happy with a gift! She was the first person I called once I'd set it up!

    Signal in new attic bedroom

    When we got our loft conversion done we found that the mobile signal just didn't work up there for some reason. When we fitted the antenna outside the skylight we found that it worked brilliantly.

    Great for Vodafone

    Since I made the switch to Vodafone, I've found that I keep losing signal in certain parts of the house. I decided to invest in this booster and I'm back to similar signal levels that I used to have with EE.

    Even works in the basement

    The basement of our house is notoriously bad for getting signal but this signal booster actually allows us to take calls downstairs, pretty amazing

    So far, works well

    I'm yet to have any issues with my booster, although it has only been a few months, hope this will continue as it works really well

    Gone from 1 bar to 2

    When I moved into my new home I was shocked to discover that there was just one bar of mobile signal compared to 4 where I used to live. It was impossible to manage with such a useless signal, but when I got this product it made a difference - not a lot of difference, but enough to ensure I don't drop calls any more.

    Signal in weak spots

    While I did have a mobile signal in my home, I wasn't very satisfied with its consistency so I decided to see if a booster would solve the problem. While this signal booster didn't give me the full five bars, it did take my 2 bars up to 3 and helped me to get a signal in the weaker spots of my home.

    Mounted Indoors - it still works

    I didn't want to go through the rigmarole of installing the antenna outside, but it works just as well mounted to the inside of my window. Much more convenient.

    3-4 bars

    I found setting this up harder than I expected, but at least I get 3-4 bars of signal now.

    As good as they say!

    I bought the booster on the strength of other users' reviews and I have to say I agree with them - this signal booster works great!

    If you have a faint signal it will help

    If you have a faint signal it will help a lot. I only get 1x connection where I live but without this, I get almost no signal.

    Works okay

    Very nice unit. I purchased used and I'm very happy with it. I have a home-based business and cell reception is low. this really made a difference, almost eliminated dropped calls completely. Only negative is short range. must be in the same room for it to work.

  25. Verified Buyer

    Just what I needed.

    The cell service in my area is very poor with one or two out of four bars normal and sometimes none.I didn't have any service in my basement at all. I now have three to four bars on the phone and even in the basement.

    Awesome service

    Thought we would have to get a new booster as the antenna wire broke. But they found us a new antenna and saved us hundreds. Thanks!!

    Simple instructions!

    Set up was simple. The key is knowing where the nearest cell tower is located for your carrier and making sure the yagi antenna is pointed directly at it. Also critical is having sufficient separation between your inside transmit antenna and the outside antenna. Went from -0- reception inside of our metal office building to 4 bars. As much as it might hurt some folks, READ THE INSTRUCTIONS!! And you will do just fine.

    Had poor, intermittent signal before. Now have 3G steadily. Will test locating outside to improve further.

    Thank you.

    I had so little faith in that the booster would work that I removed the packaging materials very carefully so I could reuse them to send the unit(s) back. Not only does the system work but it, and the support staff as well is exceptional - far exceeding my expectations.

  36. Verified Buyer

    Highly recommend!

    My internet was always shutting down because of sketchy service but since I got the unit it hasn't shut down at all. I am so glad I took the chance and bought this very booster.

    We are totally satisfied and would recommend to anyone!

    What a wonderful product! We moved into our steel shop with living quarters while our house is being built and I had NO cell signal.I work from home and needed an easy and reliable way to communicate.This product took me about 10 minutes to set up and went from no bars to 3 bars on 2 different carriers.

    Easy installation

    Very easy to install. But the performance is fluctuating. Sometimes 5 bars.. Sometime 2-1 bars. I was really happy to see 5 bars but the inconsistency is killing me. Increasing the stars to 4 stars. The only product that works for signal as weak as 1 bar.
