Mobile phone signal extender Nikrans NS500-GSM+4G PRO

To tell the truth, I am an experienced online buyer, so it was rather challenging for me to order this booster, at least at first, it seemed to me that it would be challenging. But I decided to contact a support team in order to avoid any silly mistakes and you know, the service was perfect. A very nice and polite girl (sorry, I’ve forgotten the name) explained to me every step that I should make to place an order and to make the payment. Thank you for such enormous attention to me, for the fast delivery and for my cool booster (my LTE signal increased from 1 bar to 5 bars, isn’t it a great result?)

In general, I am very happy about my purchase. The device arrived very quickly, it was well-packed and everything was perfect. But the installation was not very easy for me. I needed to ask my friend to help me. Yes, in the box I found a nice manual but for me, it was still a disaster. Nevertheless, my friend managed to install it within an hour time. NS500-GSM+4G-PRO is a very powerful device: if earlier my phone couldn't even catch the 4G signal of my operator when I was at home, now I always have 4 or even 5 bars.

I bought this device for my parents as I was fed up with their unstable connection (sometimes I needed to spend 2 or 3 hours at least to reach them just because of their mobile signal problems). When I was choosing a model for them, NS500-GSM+4G-PRO seemed to be a good variant as it is able to boost all types of signal. Now my dad even watches some YouTube videos on his phone:)

I bought this booster for my office as my employees often complained that clients couldn't reach us. For our small office, this device suits perfectly.

I am a subscriber of Orange mobile services and I never even thought that one day I would face any problems with my mobile signal. But it happened in my new office. I noticed that I couldn’t check my mobile apps on the first day at my new job but I decided that it may have happened occasionally. In the evening at home everything was okay. Nevertheless, on the second and third days, the situation was just the same. I asked my co-workers about the situation with their connection and it turned out that they were also suffering from poor connection though they all are subscribers of different operators. It became obvious that the problem was a result of the influence of some external factors.

All together we started to look for a solution and a variant to buy a booster seemed to be a good idea for us. So, we have been using NS500-GSM+4G-PRO for three months and we are 100% satisfied.

P.S. The coverage is just enough for us but our office is comparatively small.

NS500-GSM+4G-PRO is the best device I’ve ever seen. And yes, it’s not the first one in my life. As I live and work in the rural area, the issue of poor mobile connection is very pressing for me (and it has always been so). Some years ago I ordered another model of this device on another website, at first I was satisfied with it but now, when I can compare it with my new one, I realize that NS500-GSM+4G-PRO is much better. Moreover, some of my neighbors also have boosters and NS500-GSM+4G-PRO is still a winner. The device is able to amplify my GSM signal and my mobile internet connection simultaneously. And what is more important: its work is absolutely stable.

Excellent device! We installed it in our family cafe and now our guests are satisfied.

Thanks for this booster and for your professional assistance!

The booster itself s great but I was disappointed to see that it was delivered in the damaged box. I believe that it could have been the fault of the courier service. Nevertheless, the device wasn’t damaged and it works really well.

A year ago, we bought a new house. And of course, we were unbelievably happy. For us it was a very important event. The house is located in a beautiful valley surrounded by mountains. Everything was perfect but it was one detail that spoilt everything: our mobile signal was soooo poor that we couldn't’ even make calls. On the first floor, it was possible at least to catch a signal but on the ground floor...there was no chance to get connected. We realized that something should be done. We tried to reach our mobile operator with an inquiry to build a new cell tower in our neighborhood but it turned out that due to some infrastructural issues it was prohibited. So, we decided to change the situation on our own. Thank God, that at least at work I had a perfect internet connection and I managed to find this website. Now our problems with mobile signals (4G and GSM) at home are in the past. Thanks, guys, for this perfect device.

Thanks for this booster and for your professional assistance!

I live way down in a valley way out in the boondocks. I was lucky if I got one bar on my cell phone. Calls dropped all the time. I never in my life thought it would get any better. I bought this signal amplifier, and now I have 4G and four to five bars consistently. Overall, it works good, no more dropped calls or bad reception inside. I am truly stunned.so I would recommend it.

I live in the country and the cell signal only got one or two bars and unstable 4G. This signal booster really helps to increase the signal quality. Now no dropped calls and 4G Internet and I can be anywhere in my house with four or five bars! So glad we got this device! Highly recommend it!

I’ve recently moved to a cabin in the mountains. I was lucky to get one or two bars and little to no signal inside. After installing the signal booster, I consistently get 3 bars of 4G signal inside. The device and accessories seem to be of good quality. Installation and setup was extremely easy. I found a map of the nearest towers online. I would definitely recommend this product.

I bought this device for my daughter’s new 3-story home. She was able to get good reception on the 3rd floor, spotty reception on the second floor and no reception on the first floor. After installing the device on the 3rd floor, she is able to call me right away on the 1st floor and the call quality was excellent. She now gets 2-3 bars and perfect 4G Internet where she was getting none, so this device works as advertised.

My house is on the edge of mobile phone coverage. The house has a metal roof. I had to stand next to a window on one side of the house to use my cell phone. The rest of the house had no service at all. I bought this 4g signal amplifier. It took half an hour to install. I mounted the outside antenna on a pole on the roof where I received best signal. I’m very happy with the purchase.

After using this device for a little over 3 months now I can say this works. We live in an area with little to no cell reception, our home also has a metal roof. I work in IT and require the internet any time of day. So it was complete trash without this amplifier. This thing allows us to be inside and talk&text and have the hotspot connected 24/7 to the net.

We had to stand in our small state road to send texts and pictures and forget making or getting phone calls! With this signal booster we went to LTE/4G! Our phones are real phones now! I was skeptical about boosting our signal way out in the car, but this really works. We had no problems with using the product and it seems to be very solidly made. I would recommend to a friend.

Usually I don´t shop in online stores. But I decided to try with 4G booster at myamplifiers.com because my best friend had already ordered from you and was satisfied with everything. I risked and never regretted this, because your staff really helped me. I don´t know anyhting about 4g and repeaters, I just described my situation to the manager and she recommended me this model that works perfectly now! Thanks!

Without any doubts this is one of my best purchases! Covers 2 floors of our cottage y supplies perfect 4g connection and calls. I´d recommend this booster to the young people who actively use 3g Internet and live in the countryside where the signal is low.

I ordered NS500-GSM+4G four weeks ago. A week ago the device came. After the day of abortive attempts to install this I quitted and phoned to support on Myamplifiers.com. To my huge relief, they helped me to install it correctly, as I was about to demand my money back.
