NS-20K-Voice, 3G & 4G PRO Customer Stories

My best cell phone reception booster! Without it, Rogers signal problems used to kill my mobile connection.

Damien Likwa (Canada, Lloydminster)

My background story was very simple: I moved to another house and discovered that there are actually Rogers signal problems in this neighborhood. No one has told me about that before, because they were afraid I wouldn’t buy the house. So I somehow turned out stuck with Rogers signal issues when I really needed internet for my work. I had good internet at my workplace, but sometimes I needed to work from home as well, and I had to find the solution as soon as possible. MyAmplifiers were the ones who promised me the fastest delivery, and they didn’t let me down.

The best cell phone reception booster I bought because of their recommendation has arrived within a week (actually, a little faster that I’d expect), I managed to install it really quickly, and I have never experienced any Rogers poor signal since then. The manager’s recommendations also were pretty accurate, and the amplifier really satisfied all of my needs and is perfect for the size of my house. I can have stable signal anywhere, even in my bathroom, and even though I don’t really need it in here, I have tested that. Having no problems with Rogers poor coverage is such a pleasure! My work is getting done on time, and I can also have every kind of the most internet-speed consuming leisure activities, like gaming or watching TV series online.

I recommend MyAmplifiers store an their best cell phone reception booster kits to anyone who is having Rogers signal problems, because it’s really the simplest and cheapest solution you would ever find.

Telcel signal problems used to hinder my work before I managed to boost your cell phone signal!

Nathan Bitature (Mexico, Delicias)

Telcel poor signal became a problem to me. Before that, the signal I already had was enough, but now I really needed more signal bars and a more stable connection without interruptions and losing connection. I thought that maybe I could boost your cell phone signal somehow to solve this Telcel poor coverage problem in my house, and that’s how I came across MyAmplifiers. After getting a very detailed consultation, I was convinced, and it totally didn’t feel like they were trying to force me or sell to me something too expensive or unnecessary. I bought the NS-20K-Voice, 3G & 4G PRO model that they have recommended to me to boost your cell phone signal, and magic started happening.

Not only my signal went better and Telcel signal issues weren’t issues to me anymore, it also really felt like my devices’ batteries started lasting longer because they didn’t have to waste too much energy trying to “cling” on to the weak signal. It’s not that huge of a difference, but a very pleasant bonus anyway. The booster also helps me save energy by automatically going into sleeping mode when I don’t use it, and I tend to forget to turn things off a lot. That’s why smart and energy-saving devices win my heart at a glance. Telcel signal problems haven’t bothered me since, and my internet connection is currently fast and stable enough for me to cope with everything I do. The signal booster also looks nice and is very compact and comfortable to use.

Why didn’t I get one of cell phone boosters for the home for my Lycamobile signal problems years ago?!

Vincent Sherlock (United States, Fresno)

In recent weeks I purchased two units from myamplifiers.com - in hindsight I did not need to do this since one unit would have sufficed but that was a mistake on my part. One unit was to boost my Lycamobile poor signal. I have lived in my present home since 2009 and have not been able to use my mobile phone indoors as a result of Lycamobile poor coverage. This, as you can imagine, has been very frustrating. Having done some more intensive research recently I found myself on the page of MyAmplifiers cell phone boosters for the home and following some time there and a conversation with a very helpful staff member I placed an order. It arrived within days and I had it running within minutes!! The change was immediately noticeable. Just now, I disconnected the unit and took some photos. I think they will demonstrate the situation. (Please note the time on phone - these pictures were taken within five minutes and represent the quality difference made by the cell phone signal booster)

This photo, taken at 2.20pm was taken while booster was still connected. As you can see, it gives a full signal reading and I am able to make and receive calls without difficulty.

I then switched off the power switch on the unit and noticed the bars drop almost immediately to the point where there was no signal at all. At this stage, the phone was unusable for its intended purpose.

On reconnecting the power to the booster, the response on the phone was similar with total bars restored within a very short time of switching on the power.

In my opinion, this is a very clear demonstration of the difference made by the booster and I have to say I am totally satisfied with it. My one regret is that I didn’t get one of cell phone boosters for the home years ago!!

The unit I ordered is the Anytone AT700 which gives extensive coverage. My house is a two storey house (old with very thick walls) and also has a basement. I am now able to use the phone in any room within the house (including basement) and not get annoyed with Lycamobile signal problems all the time

The other unit I ordered (having been very pleased with the first) was to improve my 3G Broadband Signal. We do not have landline broadband available to us where I live (though hopefully this will be resolved at some stage) so I have been using a 3G dongle for some years. It worked but not always at a speed sufficient to usual needs. Again, I will include some photos taken today that show results from www.speedtest.com with power disabled and enabled:

The model I got to improve 3G Broadband was the Nikrans NS-20K-Voice, 3G & 4G PRO. Again this is working throughout the house ( I am using a 3G wireless router and it is picking the signal from the Nikrans). Speeds are good and have, on occasion, exceeded 5MBS.

In conclusion, I am very happy with these products. Equally I am impressed by the availability and professionalism of the sales staff. Any query I had was replied to very quickly and the questions raised were resolved. I would have no hesitation recommending this line of products to anyone and would do so in the belief that there would be professional and ongoing support provided by myamplifiers.com

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.

We ordered this booster for our sports club and we are fully satisfied with this purchase.
Support of numerous simultaneous connections, easy installation, reasonable price. I don’t know the reasons but the delivery took 3 weeks, I hoped to receive it faster.

We were impressed to see a repeater with such coverage. Some years ago, when I was looking for a signal booster for my parents’ house, I didn’t see boosters that were so powerful. Probably that’s an innovative solution. Thank you!
The price is very good for such a repeater.

I moved to Argentina not so long ago and it was an unpleasant surprise to see that the connection in our house was awful. Thank you, MyAmplifiers, for such a simple solution.

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 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.
