Gabriel Urzaiz (Venezuela, Choroni)

The booster has a lot of useful functions such as auto level control due to which the booster regulates signal gain itself depending on the incoming signal power. The repeater is equipped with MCU control so you can be sure that in case of any error the system will just reboot itself. What is more, the repeater ensures longer battery life of your mobile phone.

Sorry, I am not very good at writing reviews. Nevertheless, I want to recommend this booster. It functions just perfectly. Now we have an excellent 3G connection. Unfortunately, our operator does not provide us with a 4G signal that’s why I can’t tell you whether this device is able to boost a 4G signal (but I am sure that it is).

Purchased Nikrans NS-20K-Voice, 3G & 4G

For many years we were obliged to suffer from a terrible mobile connection. Nevertheless, finally, I understood that it was necessary to do anything about it. Thank God, today, on the internet you can find anything you want. The same happened when I tried to find the answer to the question of how it’s possible to improve the quality of the signal at home. Yes, I’ve found this website via google. At first, this idea to install an additional device seemed to me rather strange but then I studied dozens of reviews and understood that it really makes sense. So, together with my parents, we took a decision to try. Though the device is far not the cheapest one, we understood that we were so tired of problems with our cell connection that we were ready for experiments. We received our order in less than a week after placing an order. After we installed and switched it on, we realized that it was a brilliant idea to install it, the quality of our signal was improved just immediately.

Thank you for this fantastic booster. I don’t think that there are any other solutions that can be so efficient than this one. I know that many people in our country still suffer from problems with voice services and 3G internet but for our business, it is impossible to stay afloat without staying connected (otherwise, we can’t communicate with our customers). After having used this booster for 5 months, I can say for sure that it’s really worth buying it.

I’ve bought this device for our office but now I am considering an option to buy a similar booster for my home. Unfortunately, in our country, there are still a lot of areas with bad coverage. But I am happy that I’ve found this website where it is possible to order reliable boosters.

Purchased Nikrans NS-20K-Voice, 3G & 4G

Good model for reasonable price - that's my first impression. I can finally get 4 or 5 bar signal strength. I liked that the installation took only an hour, it was very easy. The only condition is to read the manual beforehand. We found a pole and tied an outside antenna to it so that the whole construction was higher, I think it works as the nearest mobile station is 20 km away from the house. Now I’ve read here that people often have problems with lightings and I think I’ll put a lightning rod next to the antenna (don’t want my booster to break down soon). I’d advise everybody who has poor signal to buy a anytone repeater, it works great!

just the ones I’ve written here – reasonable price, easy installation, good performance, clear manual, etc. It’s also nice to realize that the tool lowers the amount of radiation. lightning may be serious danger for the mobile booster.

I bought this booster 5 months ago but decided to write a review only now. During these 5 months, I didn’t have any problems with my NS-20K-Voice, 3G & 4G PRO. Its coverage is enough to ensure a stable connection in a 3-story office building. Every day at least 10-15 people enjoy the amplified signal without any interruptions. As for me, it’s not a very cheap device for private buyers but for a company, it’s absolutely affordable.

It’s such an amazing feeling when you want to make a call and you can make a call! Unfortunately, earlier, we could only dream about it. Now, it’s not a dream anymore, it’s a reality that we can enjoy. When we moved to a beautiful house located on the river bank far away from the noise of the city, we couldn’t even imagine that we would face any problems with our cell connection. Nevertheless, it happened. My wife works from home that’s why it was crucial for us to improve the signal. Especially, she asked me to find a solution to amplify our LTE signal as the main part of her interaction with clients is organized via the internet. I am not a magician but I’ve managed to make her dream come true;) Thank you! This booster is of great use for us.

I am 100% satisfied with my cellular amplifier. Ana S helped me and explained what model I need and why. Thanks for great customer service – highly recommend you!

our amplifier-extender gives additional 3 bars on average, when the weather is terrible it adds 2 but that is enough for us.

Though it’s the first booster in my life, I think it’s the best one! The only negative aspect that I can mention is that the box of my booster was a little bit damaged. But the device itself didn’t have any damages and it functions just perfectly.

The amplified signals are very stable. We didn’t expect to have such a powerful connection in our area as previously the signal quality was absolutely awful. Thank you for offering devices with such wide coverage so that people who want to install a repeater in a large building do not need to buy two or three separate boosters.

The first thing that I want to do now is to say thank you to the nice girls that work in the support team. They really helped me a lot. I am really grateful for your professional help and your attention! When I received the order needed to ask my boyfriend with the installation, nevertheless, the usage of the device is absolutely easy (you don’t need to do anything special, just to enjoy). Thank you! I’ve already told all my friends about this top-notch device.
