Led Signal Indication explanation:
LED Status
Band 1 UL/P If the light is light then there are no phone calls in the coverage area or cell phone does not contact BTS.
Band 2 UL/P If the light is red then there is a phone call in the coverage area, or cell phone contacts BTS periodically
Band 3 UL/P The constant RED light indicates System Warning. The repeater works in abnormal state or is self -oscillating.
Band 1 DL/P If the light is dark then the amplified signal output power does not reach lighting threshold. Output power is ≤ 10dBm. This means the repeater works at small power output state
Band 2 DL/P The green light means that the amplified signal output power reaches lighting threshold. The repeater works in good amplification state. The repeater works in good amplification state.
Band 3 DL/P Red or Orange light means that the repeater works in best amplification state, output power reaches maximum

    Strength goes down outside of front room

    I bought this to improve my mobile signal in my front room and while there is a noticeable difference when I'm in there, once I head further into the house there's very little difference at all, if any.

    I'm fairly satisfied. Gone from 1 to 2 bars in two of my rooms and up to 3 in the rest.

    Works in the country and in the town too!

    I bought one of these for my flat (I live in the suburbs but the signal was terrible). It worked like a dream so I got one for my sister who lives in quite a remote location. She finds it works just as well for her too.

    Great product

    This signal booster did absolutely everything I hoped it would. I couldn't be more satisfied with how well it works. I would definitely tell everyone to go out and get one.

    I really love this

    I really love this device, it has improved my everyday life so much from just web pages loading faster to clearer calls. Simple things, but they really matter to me.

    I have a phone registered with O2 and this signal booster works very well with it, always getting four bars at the very least

    Suprisingly good

    After debating whether I should get a signal booster for months I went ahead and bought one and I have to say that I am impressed, I consistently get at least four bars

    Has given me 4 to 5 bars where before I purchased this booster I had a red x on my bar symbol.I live in a rural area so this was just what I needed in order to receive the signal for some good service.

    Works Oustanding

    Wow, this thing really works well. I work in a metal building with NO cell service. I ran the exterior antenna outside and connected it to the interior antenna and - BOOM!..........GREAT Cell Service inside..........I highly recommend!!!

    Full signal

    I live in the country and barely got one bar for a signal. Now sitting in the same room with the antenna I have a full signal.
