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.

I am happy that we have bought MA-500C for our house! Excellent device, excellent service, excellent professional help and excellent web site! I am so happy that we have found out that today so many mobile signal problems can be solved with mobile signal boosters. I really have had no idea that today it is possible!

I am really happy that I decided to order a booster on MyAmplifiers.com. 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.
The coverage is amazing. We placed this extender in our supermarket to ensure a better connection for our staff and customers.
It is a very powerful device with a good coverage. We installed it in our supermarket to help our employees and customers have a stable signal. Thank you!
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).
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.
We ordered this booster for our sports club and we are fully satisfied with this purchase.
Thanks for this high-quality booster.
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.
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.
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.
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.
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.
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!
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!
