MA-300GDW Customer Stories

Hi-tech booster that spared us of Lebara signal problems!

Grace Meakin (United Kingdom, Colnbrook)

Eventually, it turned out that it happened not because of the provider, but because we had Lebara poor coverage in general. To fix it, we needed a good signal repeater, so we turned to MyAmplifiers store for help. And we got a perfect result out of it! After we bought and received our booster, Lebara signal problems were instantly gone and now our internet connection (as well as GSM signal) is good and stable in every corner of our house. The internet speed is high enough for absolutely everything, and all of my family is very happy about it. No more Lebara poor signal and lost connection: now we can have high-quality calls even from our basement or bathroom and we can watch videos from our phones in bed, and they will load very fast.

The signal repeater supports all of our devices at a time and no matter how many of them there are, it doesn’t affect the working quality of the booster. Neither does the weather, and it’s often humid and relatively cold in the place where we live. No matter if it’s snowing or raining or the sun shines directly at the outside antenna, everything still works fine. If you have any Lebara signal issues as well (or any other operators), I would totally recommend MyAmplifiers to you because of their outstanding service, high-quality products and fair prices.

Brilliant service and mobile phone booster! I'm free of Elisa signal problems!

Elias Virtanen (Finland, Hyvinkää)

When I’m talking about service I mean the unbelievable dedication of the workers to customer service. I was incredibly pissed with all my Elisa signal problems and started the search for a signal booster in a ‘not so great’ mood. And when I stumbled into MyAmplifiers website, I felt like I really need some consulting, because the variety of signal boosters is huge. But it was that time of the day, where the pop-up message told me that the client support is out of office. I got angry at the whole company, left a message and went to bed, still dealing with Elisa signal issues as I tried to scroll through my Instagram feed. The next early morning I received a wonderful message from the client support and they did not only offer their help in choosing the perfect mobile phone booster, but they also proposed a discount for my purchase! I simply loved such an attitude.

Product. I received the mobile phone booster in only a few days. The quality of the parts was brilliant and the package had everything I needed to install the thing on my own, so that I can finally cope with Elisa poor coverage. It took me around 12 minutes to get the booster working. I had absolutely no problems with the device since day one. No more Elisa poor signal issues anywhere around the house. Moreover, my 4G booster is 100% safe for your health and I love-love-love that as well. THANK YOU!

I said 'Good-bye! to signal issue with POST Telecom phone signal booster

Damien Feimer (Luxembourg, Mamer)

I felt like having a flawless GSM, 3G and 4G connection in the 21st century is a normal thing, but here we are. Various POST Telecom signal problems simply became horrible. I would have to wait for long minutes for a message to be sent, wasn’t able to receive important calls and having a video-conference was a whole battle with POST Telecom poor signal.

I found out that there are such things as a phone signal booster. And, turns out, a lot of the people I know are already using these things. But one friend of mine spent a whole fortune on his signal booster; another wasn’t really satisfied with the quality of the device and so on. Even though I really do think that you have to invest into a great signal booster (yes, you have to think of that as of an investment) I wasn’t really ready to spend over eight hundred dollars on dealing with POST Telecom signal issues.

That was when I started surfing the Internet and I stumbled into a wonderful company – MyAmplifiers.I didn’t even start worrying about the delivery, because I received the phone signal booster kit only 5 days after I placed the order!

The package had everything I needed. I was surprised to find out that the thing starts doing the job as soon as you finish the installation! I had no problems with the device, POST Telecom poor coverage is not my issue any longer thanks to one of GSM 4G signal booster!

MA-300GDW is a good device. I installed it five months ago, and since that time I haven’t had any problems with it.
Quality of the device. Its price.

Purchased Nikrans MA-300GDW
It’s a great thing! Frankly speaking, I have never regretted the purchase. The booster is very helpful, especially at the cottage, where I have no mobile coverage at all. After the installation the signal has become better and more stable. The only minus is a little bit high price, but it’s worth it!

Thank you! There is nothing bad that I can say about my interaction with this company. The quality of the device is even higher than we expected to get. It works efficiently, and our connection is finally stabilized.

If you want to buy a booster but still have some doubts, I hope that my words will help you to make the right choice:) I do not regret buying this booster, even though initially I also have a rather skeptical opinion.
Reliability and power of the device.

Cool booster:) I have nothing to add:) Probably you need to install it at your place to understand all its benefits.

Excellent repeater and excellent company! Thanks! I am happy that I managed to save money to buy MA-300GDW.
Compact sizes, easy installation, seamless work. There are no showrooms in our country. But it would be cool if a customer could touch the device before ordering it.
Portugal, Verified Buyer
Purchased Nikrans MA-300GDW
Even though my parents didn’t believe that just a strange box with two antennas would help us to improve our mobile connection, I still ordered this booster. And can you imagine how surprised they were when they realized that it’s really helpful? The coverage of the device is not very wide, but for our flat, it’s more than enough. Unfortunately, our dog has spoilt one of the cables, but I’ve already ordered a new one. Hope that it will have a longer life than the previous cable.

Purchased Nikrans MA-300GDW
I moved to Ravensburg just a couple of months ago when I decided to start my studies there. The town itself captured my heart just at once. But I needed to solve a couple of issues before I could start enjoying my student life. The first thing was to find a flat (I managed to do it rather quickly). And the second thing was directly connected to the first one: to find a way to improve my mobile connection there. At first, I thought that maybe the mobile operator that I chose was not a very reliable one. But my neighbor told me that subscribers of all carriers who provide their services in the country have the same problem. He also recommended me to buy a booster just like they all had already done. I found MyAmplifiers website and was impressed to see such a wide choice. I didn’t need something extraordinary that’s why I ordered MA-300GDW. I think it’s just something of the middle class. And you know, it’s cool. It improves all the types of signal and works without interruptions.

I bought this signal repeater for my parents. They are 100% satisfied. Now they can enjoy excellent connection without any special efforts. By the way, my dad installed the device on his own and was extremely proud of himself :)

I purchased a Nikrans NS250GDW, Anna was a great help with pre-sales questions I had, and recommended the product to suit my needs. Regards.
Bulgaria, Verified Buyer
Purchased Nikrans MA-300GDW
Many thanks for this repeater. Usually, I don’t make such serious purchases online, and I don’t read reviews. But a booster is a quite specific device, so I didn’t manage to find a good variant in traditional shops (the majority of the devices that I found were either too expensive or too weak). As I don’t like online shopping, for me, it was quite stressful for me to place an order, but everything was okay. I didn’t have any problems with payments, the order arrived quickly.
Macedonia, Verified Buyer
Purchased Nikrans MA-300GDW
It’s definitely 5 out of 5. The only disadvantage (or the aspect that can be considered as a disadvantage) is the price. Unfortunately, I know that not all families can afford it; for example, my parents couldn’t. But I bought it for them, and they are very happy.
Belgium, Verified Buyer
Purchased Nikrans MA-300GDW
I don’t know how it happened, but when I was analyzing different models of extenders to make my perfect choice, I didn’t include this one in my shortlist. Maybe it happened just because I hadn’t noticed it or due to some purely technical issues. But after my first “round of analysis”, I didn’t find something that I wanted. I was ready to give up but decided to contact the sales team in order to ask for their recommendations just to be on a safe side. And after listening to my story, Anna recommended me MA-300GDW. I was surprised to see this booster, but I liked it. Practically immediately, I placed my order, and in 6 days I got it. The amplifier really turned out to be so cool as I expected.

This device is a very good if not the best solution to mobile signal problems. I’ve chosen an amplifier which improves both voice connection and mobile internet. The characteristics were suitable for me (I mean the working frequencies and the indoor coverage). The result of the amplifier’s work is really impressive. Stable connection and speedy internet!
Portugal, Verified Buyer
Purchased Nikrans MA-300GDW
Just installed this booster. Lost some time to find the best location for the antennas and to run the cabling inside the house, but once installed the booster did not keep me waiting for the result – 5 bars instead of 2. Plus, 3G Internet without interruption. Highly recommend this!
All features function as advertised. Covers the whole house and a bit of terrace – nice for the summer bbq’s)) Delivery took a week, but that is no big thing providing what I got.
Malta, Verified Buyer
Purchased Nikrans MA-300GDW
The booster is very comfortable to use. I didn’t install any software and didn’t buy any mountings for the set up. All necessary accessories were sent together with the amplifier and the antennas and I managed to install the device on my own guided by the instructions given. Works perfectly, without any complaints.
Spain, Verified Buyer
Purchased Nikrans NS250GDW
This is a fantastic device! It works on 3 frequencies at the same time and suits for ALL providers of Spain! Perfect coverage, easy installation. Also want to say thanks for friendly support.
Above I describe everything - I´m completely satisified! Over 1 week waiting for delivery.
Brazil, Verified Buyer
Purchased Nikrans NS250GDW
Super satisfied with the booster. Significantly improves phone calls audibility, 3G Internet quality. The delivery was fast, tracking option. The device is simple yet complete - you have all to set up the system and get perfect conection.
Quite low-priced for good quality. Perfect for those who needs a booster for small area but with all possible frequencies in one device. Indoor antenna could be more powerful.
