Customer Stories

Mobile repeater managed to improve cell coverage and COOPVoce signal problems in my parents' house.

A signal amplifier is a very convenient and easy solution that improves the signal no matter how bad it is and allows me to get the best out of my GSM and 4G signals. The internet speed is high in any corner of the house, and I can make phone calls even from the basement. It also fits inside the house easily, because it’s a small device that only has a couple of wires. Overall, I like that I bought it and I would recommend it to anyone just as it was recommended to me.

The site offers many models to get the best signal for mobile phone Vinaphone.

I now have stable Internet connection. The signal during the calls is flawless. And the booster also managed to improve my 4G. I can’t recall the last time I was so extremely happy with a purchase. A signal phone booster is a great investment. And I will surely be buying another one for my office!

Telecom Liechtenstein signal problems are not our reality anymore. We have best mobile phone signal

I live in Liechtenstein which is famous worldwide for its wonderful nature and landscapes. Unfortunately, because of its Alpine location the country quite often suffers from insufficient mobile signal, especially Telecom Liechtenstein poor coverage in such rural areas where my country house is situated.

Quick delivery despite COVID-19 outbreak

I am really happy that I decided to order a booster on Due to the pandemic of coronavirus, we have taken a decision to stay at home. But of course, in our case self-isolation could have presupposed full isolation from the whole world as the quality of our mobile signal at home used to leave much to desire.

Customer Reviews*

Purchased Nikrans NS-550GDW

Though I use this booster at home, my boss is already considering the possibility to buy it (or a similar model) for our office. So, it’s highly possible that quite soon I will write my second review. Nevertheless, given my current impressions, I believe that the following one will be also positive. As I live in a very small town in the south of Germany, it’s quite common for me to hear that somebody has problems with a mobile signal. The closest cell tower is rather far away which is the main reason for our troubles. As I stay to work from home quite often, I needed to solve this problem. That’s why I bought a booster. My GSM signal is perfect now. As for 4G, sometimes I have 4 bars instead of 5 but I don’t think that it’s a disaster. So, thank you, guys, for this booster.

We’ve been using the booster for 4 months and I can say that we are still absolutely satisfied with it.


G (United Kingdom)
Verified Buyer
Purchased Nikrans NS-550GDW

We bought this booster for our office. We work in a business center in the suburbs of London and as our operator has explained to us the main problems with our connection are caused by the peculiarities of construction material used for our building. But as you know, today it is absolutely impossible to do business and to stay isolated. That’s why we decided to buy a booster. Our company occupies the rooms situated on one floor, so, we didn’t need to have a device with very wide coverage. We also didn’t want to buy something extraordinary. We needed just a simple but powerful device. After consultation with a manager of this online store, we chose NS-550GDW. It arrived just in a couple of days which was a pleasant surprise. The device fulfills its functions perfectly. Oh, it’s a funny story: some guys from other companies from time to time ask us whether we have noticed that the mobile signal has become more powerful (they don’t know that we’ve installed a booster).

Purchased Nikrans NS-550GDW

When I got my booster, I was a little bit disappointed to see that the box was damaged (I think that’s the fault of a courier service) but with the device, everything was all right. it functions well and my connection quality is improved significantly.

N (Austria)
Verified Buyer
Purchased Nikrans NS-550GDW

We live in a cottage and without a booster, our mobile phones couldn’t catch a signal on a ground floor. As you can understand, it’s not very convenient to go upstairs each time when you want to call somebody or when you need to send a message. Moreover, if my phone was on the ground floor, I couldn't even know whether I’d already received a reply to my message, for example. So, the booster has definitely saved the situation. Now we have a stable connection in all the room.

Purchased Nikrans NS-550GDW

The amplifier is installed in our office and we all are very happy that we’ve bought it.

Amazing power. At first, we got some problems with an outdoor antenna (we couldn’t fix it) but then everything was okay. We managed to install it in a proper way.

A (Poland)
Verified Buyer
Purchased Nikrans NS-550GDW

We bought this device for our private house (it’s rather small that’s why the coverage of this amplifier is more than enough for us). You know even 4-5 years ago when we used a landline phone, the problems with GSM signal seemed to be not so serious. But now our mobile phones remain the only means of communication. When we started looking for a booster, they all seemed to be very expensive for me (if they were cheaper, the reviews were awful). But this one met all our requirements. So, when we installed it, the difference became obvious. We are happy that we bought it.

I bought Nikrans NS550GDW amplifier from the company. I am totally satisfied with the customer service. My helpdesk agent was Ana S, who made a remarkable job. She was helpful, always wrote answers immediately. She was helpful with my issue of the payment too. I can just offer this company for amplifier services.

Verified Buyer
Purchased Nikrans NS-550GDW

I would recommend this product simply for its price and coverage ratio. My old repeater has very poor range in my house, and I often had problems with gsm signal reception - that was really annoying!

Before I installed the Nikrans booster I read through the online FAQs on and the manual - the installation was ever easy! Besides, it is great to have a amplifier that finally works! waited rather long for my package - but now that does not matter

I will express myself in english because i am confortable that way, so I received the amplifier, i was skeptical in the beginning because i used different amps in the past with poor results but this one really works! I am really satisfied. I guess every amplifiers are not equal.
