—— CARLOS GREGORIO,United States

Let’s be honest, the quality of my Vodafone mobile signal at home always left much to desire. I just was too lazy to do anything with it. I was absolutely satisfied with the rates and the quality of the signal that I had everywhere and my own house was an exception. However, the coronavirus pandemic changed everything. I started to spend much more

—— Ali , Spain

I bought this booster for my apartment because I was absolutely dissatisfied with the power of GSM and 4G signals that I had there. But now the situation has changed. Thank you for this booster, I finally don’t feel isolated when I stay at home alone.

—— Abdul Mohammed,Germany

I think that’s a very nice solution for those who suffer from problems with voice services and mobile internet and do not want to create any antennas or smth like that themselves. The price is absolutely fair and the quality is amazing.

—— Lena W.,Finland

I was very happy to see the discount that you offered. I know that quite often companies make discounts on goods that are not popular but in this case, I see that the situation is quite opposite. I like that this device is able to improve calls and the internet speed at the same time.

—— Giulia M.,Austria

Thank you! The booster is super cool for a private house. All the rooms are now covered with the improved signal. Now I can’t understand why we haven’t bought it earlier.

—— Nadine Nacht ,Germany

It’s a very cool booster! Thank you, dear team, for your attention to your clients’ needs and the prices that you offer. You are the best, ATNJ

—— Natalia L.,Norway

My 3G and GSM connection used to leave much to desire. But with m new booster I have practically forgotten all these problems. I really like that this device is so compact but so powerful. Thanks, guys, for your amazing work and fast delivery.

—— Goran N. ,Sweden

I can’t understand why I bought this repeater only 2 months ago and not earlier. That’s a very useful device for those who live in a rural area like my family. The improved quality of connection has significantly improved the quality of our life.
