    Installed in a second-floor apartment. The antenna was placed on the roof of a five-story building, the external cable just reached the second floor. As a result, from 1 to 2 bars and not being heard on the call, it went to 4 to 5 bars of signal. It even picked up 5G (for the Vodafone network). Finally, easy installation. Very satisfied with the result.

    While it seems that we have signal in the basement where I installed it, many times we cannot receive incoming calls. On the contrary, when we want to make an outgoing call, it works perfectly. Maybe I didn't set something up correctly

    The signal booster is very good; I don't think it is for 300 meters as it claims, but I am doing just fine in a difficult area with a 6-meter pole for the outdoor antenna

    The device does what it promises. I have full signal on my mobile phone inside the house 4g+. Those of you who have a problem need to ensure that the internal antenna is 15 meters away from the external one, or if they are closer, a wall should be in between. The external one has a clear line of sight with the mobile antennas because I know where they are in a straight line 3.4 km away; I also have one at 1.5 km but without a line of sight. Before, I had no 4g at all in the house. Finally, be careful not to install the antennas on the amplifier the wrong way, because I did that and had terrible signal!

    In an area with a general problem with mobile signal quality, the antenna was placed on the roof and the transmitter in the basement, which never had a signal. The result is that now the mobile phone is fully functional. So the device did what it was supposed to do.

    It actually works, it does what it advertises to do, AS LONG AS you set it up correctly, meaning you aim well with the external antenna.

    Perfect!!! From no signal at all inside the house, I managed to have full 4G and 48Mbps internet speed with a 4G router!! Without interruptions and disconnections.

    I went to a well-known telecommunications company because I had a problem with the signal of my mobile phone. It was on the ground floor, so I had to go outside to get a signal. They told me that they don't have a device for that. I had seen this device on the internet and I was a bit hesitant if it would work, but in the end, I tried it and I am very satisfied. It works perfectly, the signal is strong and it doesn't lose connection at all. It also has a very easy installation. It saved me! I have placed the antenna high on the 3rd floor

    Such a waste of my money... This doesn't give you a signal, it sucks it up. I wonder where other people found improvement in their signal... in order to find a good spot for the antenna, you have to see where the wind is blowing today or make a deal with the devil. 130 euros thrown in the trash. Stay away.

    We got it for the vacation house since it had very limited mobile coverage and no internet at all, and luckily everything works and functions with all providers. Finally, we also have 4G internet.

    I am referring to the model of 150+ euros with 4g plus...
    I don't rate it five out of five because it has some details that I need to analyze.
    In general:
    Initially, it performs its job very well.
    Mobile signal is always full, regardless of whether it has good 4g connection or not. The signal range is decent, but for 4g, you need to be relatively close because it drops significantly after a certain point.
    Placement:
    In general, you will have trouble finding the right spot and the right positioning of the antenna to achieve the maximum result.
    For example, I was interested in having a good 4g internet signal and so far it has about 70mbps at the spot where I have it, I can do better but at least in my case if I move it inches (the antenna) the connection quality may drop by half.

    Approximately 20 days ago, I bought the ATNJ GSM 4g 1800mhz Signal Booster for my village because I don't have a landline phone (internet) and the signal from Vodafone is weak. Generally, the plot of my house in the village is 1 acre. I bought a 3-meter PVC pipe and installed the external antenna on it. Initially, I placed the pipe with the antenna inside the plot and had the booster inside the storage room. I tried rotating the antenna to find the best signal using Vodafone antennas and also used the OpenSignal mobile app in vain. I raised the antenna with the pipe to the 1st floor, and the reading I was getting was around -48 to -54dbm for outdoor and approximately +7 to +21 for indoor. When the mobile phone was close to the booster, it had a full 4g signal, but when I moved two meters away, it would drop and show +H.
    I consider this particular product to be garbage, and it's a shame because I wasted 129 euros. If you have an opinion about this product, I would like you to write it.

    It is not an amplifier, it just transfers the external signal inside the house

    It has improved the signal quality quite a bit, for its price it is fair.
