Customer Stories

Hi, everybody! I am writing from Uganda. Maybe you think that in our country there is no mobile phones, then you are not right. Of course, the level of development of mobile network infrastructure may be really lower than in the leading world’s countries, but still we have excellent mobile services. Yes, there can be some signal problems (personally I have faced with Africell signal issues), but as I can see from the posts made on MyAmplifiers web site, people all over the world can suffer from poor coverage of the signal of their mobile operators.

Ooredoo signal problems? - None anymore!

Craig Mainz (Qatar, Mukaynis)

I didn't want to put up with Ooredoo signal problems in my area and started looking for some sellers where I could acquire a mobile signal booster. This search led me to MyAmplifiers web site. And not only I got perfect, remarkable service, I also received my purchase really fast, in full kit, with no need to buy any extra details. That’s not what you often expect from online sellers. I am very grateful that MyAmplifiers gave me an opportunity to make my life much easier and not refuse all the perks of living in a modern world.

I was on the search for a signal booster that would exclusively work with 4G/LTE Internet, as this seemed to be one of the biggest Three signal issues. I have to say that I am quite picky even when I’m food shopping in the supermarket. But when it comes to spending more than three hundred euros at once – I have to make sure that everything is perfect.

Nikrans NS-GDW-Drive is the first car cell phone repeater I have tried. I would like to share my experience, which actually was rather positive. I have two children and my parents live in the village. So practically every weekend we escaped from the nosy city life to the countryside. The only problem was that on our way to my parents’ house we suffered from A1 poor mobile signal. I couldn’t make calls and my children complained that their mobile internet didn’t work properly.

(Portugal)  ·  Purchased Nikrans LCD250-4G PRO  ·  15-01-2019

Solid product. This company makes really great stuff. Works great. It does take some effort getting it pointed in the right direction. You need to mount the antenna at least 20ft away from the transmitter to get a good signal. Used to have only one bar or none. Now we have 3-5 bars all day. A remarkable difference in 4G Internet! Worth every penny for fast service.


(United Kingdom)  ·  Purchased Nikrans LCD250-4G PRO  ·  15-01-2019

This device is a "must have" for me, I live in the mountain areas where 4G reception is very spotty. I haven't had a 4G/Call dropped since installing. This was a replacement for a 6 y.o. signal booster. This was one of the best things I’ve ever purchased. Takes a weak signal and boosts it to be very reliable. I'm quite impressed with this gadget.


(Denmark)  ·  Purchased Nikrans LCD250-4G PRO  ·  15-01-2019

Installed at my lake house, cell signal before I installed was spotty at best. Now I have a very good and reliable GSM/4G signal. Works excellent whereas before had no service. Everything you need is right in the box. This device boosted my signal from one bar to 3-4 bars. Have recommended it to others, now 2 other family members also purchased and have had the same results.


(Belgium)  ·  Purchased Nikrans LCD250-4G PRO  ·  15-01-2019

Was given information on this product from a friend. What can I say? It’s an excellent product! Installation was a breeze and we now have great signal in our office. I have a sub office I plan on ordering this device for the office as well now. This amplifier is really strong. Immensely better than the model we had before. Made everyone extremely happy.


(France)  ·  Purchased Nikrans LCD250-4G PRO  ·  15-01-2019

I mounted this thing in my RV. The external antenna is on the back of the RV, the inside antenna is in the front of the RV. The outside antenna points east and the inside antenna points north. The signal amplifier does boost the signal. Awesome product!!! I now have cell service inside my RV. Data is pretty fast too.

Gets the job done, but costs too much.


(Spain)  ·  Purchased Nikrans LCD250-4G PRO  ·  15-01-2019

This booster has done a great job at increasing our cell phone signal to a level that is quite usable. As it states in the instructions, it can only do so well when it receives a low signal. Went from 1 bar to 4 and no gaps in 4G service. You need to do a proper installation for the booster to work, but if you do you will be rewarded with a solid signal.

Nice product. Expensive, but worth it.


(Italy)  ·  Purchased Nikrans LCD250-4G PRO  ·  15-01-2019

The home mobile signal booster does what it says it will do. We went from barely one as at a single window to full signal all over. Our house is insulated concrete forms with metal roofing. I am very impressed. Has been working great. I am able to stream data and make a phone call. Wonderful to have if you work remotely and are in poor coverage areas.

Makes the signal stronger and more reliable.


(Norway)  ·  Purchased Nikrans LCD250-4G PRO  ·  15-01-2019

I thought long and hard about purchasing this device because it was too expensive. I have a metal roof and I was lucky to get one bar on my smartphone. I took the plunge and purchased this amplifier and could not be happier. I am able to make calls with a good strong signal. I get full bars in a couple of rooms in my house and in other rooms I get 2 to 3 bars but the connection is good and solid.


(GB)  ·  Purchased Nikrans LCD250-4G-PRO  ·  10-03-2018

For a geezer like me easy installation is essential. Finding the optimal position for the repeater and the power supply as well as right direction of the external antenna was the only glitch for me. Steady mobile signal reception, good performance, reasonable price - I do not need more.

My needs are simple so all the advantages mentioned above are enough for me.


(Norway)  ·  Purchased Nikrans LCD250-4G-PRO  ·  06-03-2015

i was speaking on line with Yana and she was very helpful so i will visit the local globe and smart provider to double check the exact frequencies they are working on if it is 4 g lte or 3 g before i order the repeater from your company

Good support
