I am completely fond of the booster. It fulfills all promised functions I read on the official website of your company. I was slightly disappointed with paid delivery to my country. However, 20 euro for this is not the sum of money against the quality of 3g connection and GSM and I was delivered the amplifier directly to my apartment. Recommend!

I am currently living on a campus of a university not far from the mountains. The fast half a year my friends and I didn’t have any problems with 3g connection or GSM but a couple months ago we began suffering from a bad signal. So, my friend’s parents brought us the model NS-300 GW and a special man installed it for us within two hours. I saw that a set had a repeater, two antennas, and a power supply. We were amused when the signal became great not only in our room but the following 3 rooms found out the same thing. It’s great that it can work extensively.

To tell the truth, when we ordered the device, I didn’t have any special expectations as I really didn’t know what to expect. However, now I am in love with it. It’s fully worth the entire amount that we paid for it and I think that if somebody asks me about this booster, I will sincerely recommend it.

I use the NS-300 GW model for my office and didn’t notice the negative sides of the booster. It totally helps us with a good connection and I am not going to purchase a new one. I am really grateful to the support team which assisted me in choosing and sent an amplifier after 2 days I ordered it. Very quickly!

When I just installed the booster, I was ready to return it as it didn’t work. But the problem was that I forgot to switch it on. Yeah, things happen:) So, be very attentive, guys. The booster is cool!

Purchased Nikrans NS-300GW

We work in a VERY rural environment in Uganda and purchased three units in all. The purchase process was quite smooth. in one location we put in the Nikrans NS300 and in the the other two locations we put in the 450 model which work great. After a short time the NS300 simply stopped working. So upon our return home I made contact with Julia who was very understanding and quite professional. The unit was eventually diagnosed and replaced without fuss. I reply appreciate the professionalism at MyAmplifiers and plan to purchase other units in the future.

The device looks very modern. At first, I wanted to buy another model that was even more expensive but Alice (sales manager) helped us to choose this repeater as it also perfectly met our requirements but was a little bit cheaper. Thank you for your honesty!
