    I thought this would be a cheap knock off product. But it is actually very well built and effective. I've gone from 1 bar to 4 and 5.

    Working ok

    Seems to work reasonably well after trying multiple locations. Had issues finding a good area with enough reception.

    Connected at last!!

    After weeks of minimal and sometimes non-existant mobile reception since moving to a country residence, I am delighted to be able to answer calls from most parts of my house. The whole experience with Signal Boosters has only been slightly marred by the omission of an extra indoor aerial ordered, but to give them their due, Signal Boosters have been very prompt with their replies and have promised to send the missing parts by express post.
