Thanks! Everything is okay. Though, as for me, the device looks quite strange but its design is not a key parameter. The stability of its work is its main advantage.

My mobile connection is much better now.

Excellent booster. Arrived faster than we expected. It is absolutely easy to use it even if you have never seen anything like that before. The coverage is probably even slightly wider than it is stated on the website. Highly recommended!

I do not remember already who advised me to look for a booster to improve our mobile signal but I am very grateful to this person. And of course, I am very grateful to the MyAmplifiers team for excellent support service and high-quality devices.

Thanks for that excellent support service!

In general, it is good. The standard cables were too long for my place. There is a possibility to customize a standard kit. But the issue is that you can order even longer cables, not shorter ones. As a result, now I am afraid that my booster may function incorrectly.

I like the website so much! It took me just 5-7 minutes to choose a booster and some minutes more to place an order and pay for it. Of course, I carefully studied all the reviews and customers’ stories beforehand. And it’s also cool that they are available.

The device works perfectly.

LCD-300GW was the first booster that I’d seen in my life. But I managed to install it without any external help. Can you imagine? I didn’t expect that I could do it. Nevertheless, I think that it’s a bright proof of the user-friendliness of this amplifier.

The mobile phone signal booster I have bought at MyAmplifiers is one of the best bargains I have ever made. It perfectly improves poor signal and ensures stable mobile connection in the house.

For a couple of years, we’ve been using a similar device in the office and now I decided to order this one for my grandparents who live in the countryside. They said that it was the best present for them ever.

Even my grandparents can easily use this booster and enjoy a very strong signal. For elderly people, it could be quite unusual to make purchases via teh internet. However, I do not think that it can be viewed as a disadvantage. Let’s better say that it is a specificity of such business.

I shall say that this repeater is the only device that have supplied us with good coverage throughout the house. We have tried several antennas and DIY devices... and nothing. But this repeater improves the signals of Movistar and Vodafone that we use, and it also gives us stable 3G Internet connection. Economic, of compact size, easy to use, really durable and of incredible power. For me and my husband it´s also important that it doesn´t affect our health negatively.

The device is the best solution to mobile signal problems. I used to suffer from poor mobile coverage in my countryside house which was located in the village. But hardly had I installed the amplifier when all the signal issues disappeared. Immediately after the set up my mobile phone showed five bars and the quality of 3G connection became much better.
