GSM 4G/LTE Cell Phone Repeater for Home Nikrans NS-550 GSM+4G

To tell the truth even when I placed an order, I was not sure whether it was a good idea to buy this booster. However, now I regret not buying it earlier! :)

Thank you for a high-quality and powerful device. The real features of the booster fully correspond to the description on the web page.

Thanks! The order was delivered very quickly. We didn’t have any problems with installation but at first, my phone couldn’t catch the improved signal (though my mother’s phone caught it immediately). I don’t know why and how it happened but the next day everything was okay. Since that time, I haven’t had any problems.

When I received my order, I was very disappointed to find out that something was wrong with one of the cables. Though at first glance everything was already when I connected my outdoor antennas with an amplifier box using it, it became obvious that the cable was damaged. I contacted the support service and just in a couple of days, I received a new cable. The first impression was a little bit spoilt but now everything is alright and I am very satisfied.

Guys, thank you for this amazing booster and for your amazing work. I was really impressed with the quality of your work. To tell the truth. I am a very demanding customer, especially when it comes to online purchases. I want to know everything about the product before I order it. I think that I have called the support managers for 4 or 5 times (maybe more, I don’t know) and each time I have asked hundreds of questions. But I’ve always received very detailed and very professional replies. Though later I have found out that all the information that I needed is presented on the website, the managers remained extremely polite and patient. The device itself is also cool. It functions without any interruptions and ensures stable GSM and 4G coverage (I couldn’t wish more).

Cool thing. I have already recommended it to my neighbors with similar mobile signal problems.

I think it’s a very good device for an office situated on the ground floor (but in reality, it’s practically an underground floor).

For me, it was a real discovery to find out that something like these boosters is available today. Though I was suffering from problems with my mobile signal at home for a couple of years, I couldn’t even imagine that one day this problem will be solved so easily. It was my friend who sent me a link to this website. I don’t know where he had found it but my family is very grateful for him. So, we ordered this device because (first of all) the price seemed to be very attractive and it had all the functions that we could wish. Now after we have installed it, the internet connection is just perfect, it is amazingly stable and the speed is really high. The quality of voice services has been also improved but to tell the truth we all use the mobile internet much more often than our voice services.

Thanks for this amplifier. It suits me perfectly and is able to improve our awful GSM and LTE signal. At first, I wanted to order two separate boosters for these two types of signal but when I contacted a manager for a consultation, she explained to me that this one would be enough. I am very grateful that thanks to her professional help I could save my money. It was very easy for me to install this device and there are no problems with its functioning.

Thanks for a high-quality device. Earlier, in our house, our GSM signal was so bad that we couldn’t make calls and there was no 4G coverage at all. Now I can even watch films on my smartphone and make video calls!

I am very happy that my dad agreed to buy this device as earlier he didn’t want to buy it due to his fears concerning the possible harm that such boosters can cause to our health. I needed to spend hours explaining to him that they are not dangerous. Thanks for useful articles on the website. I used this info to convince him.

Thanks, the device is awesome. We bought it for our office. Though some members of our team didn’t believe that any amplifiers could help us, they were wrong. The booster turned out to be exactly what we need. Now we can communicate with our clients without any troubles. By the way, the delivery was so fast that we were really surprised to see a courier standing at the door with our box so early.

I bought a gsm+4g amplifier for our house, located 30km from Madrid. I installed all the equipment in a hour, even not having any technical background. The most important is that my family is satisfied, my children can make calls from their rooms and my wife can telephoning from our kitchen. In my opinion the price is not so high for 500 m2 coverage capacity.

I decided to order this GSM+4G booster from Myamplifiers.com as my best friend have bought from them and said I could trust this company. I risked and don’t regret as they helped me a lot. I don’t know anything about signal booster sets, I just told them how big is the office building, how many storeys it has and what I want from the equipment. Then they gave me detailed information, explained the ins and outs of its performance and advised me this Nikrans booster, and it works excellent! Thanks you, guys!

I LOVE THIS BOOSTER and all myamplifiers staff! They saved me from boring life!! I couldn´t use my iphone and the worst no facebook!!! you saved me!!! Huggggs!!!!

Thanks for all MyAmplifiers' team for your help in choosing the right booster for me. I like everything, functioning, attractive price, quick installation and fast delivery. This repeater works well with our provider MEO and covers two floors of our small house. Also it supports 5 mobile phones in the same time without any interference.

My first impression of this booster was great: it is an excellent amplifier for a reasonable price. Finally my phone can catch 4-5 bars of signal. I also liked an easy installation, it took me only 1 hour. The most important is to read the user guide first. I found a right place and fixed the outdoor antenna so it was as high as possible. I've heard that many people suffer from lightning damage of outdoor antennas, so I decided to put a lightning conductor close to my antenna. In general, i would recommend this amplifier to everyone who suffers from very pour signal in the house.
