Be careful for self-oscillation

I bought this booster a month ago and couldn’t wait to test it. So, what can I say? This is a very effective device. It easily amplifies poor GSM and 3G, but only on condition that you install it properly. It’s important to create a good isolation between the outdoor and indoor antennas, otherwise self-oscillation may appear as in my case. Fortunately, the managers explained me how to solve the problem.
Dear Malcolm, thank you for the review. Feel free to contact us whenever you need. Kindest regards, Support team.

 ·  Albert Neal  ·  Verified Buyer  ·  13-01-2020  ·  LCD1200-4G-D


It operates really great. When I bought the amplifier last month I didn't know it's capable to enhance the 4g signal at my apartment because it was really poor reception. Nothing supernatural, only a couple of cables and antennas, but it works.
Dear Albert, thank you for the review. We are glad we helped you. Best regards, Support team.

 ·  Samuel MacDonald  ·  Verified Buyer  ·  13-01-2020  ·  NS-Smart-Boats

Install additional antennas

My advice is to install additional antennas to provide better dissemination of the improved signal around the whole ship, especially if we are speaking about multilevel yachts as mine.
Dear Samuel, thank you for the feedback. Your opinion means much to us. Kindest regards, Support team.

 ·  Oscar Richardson  ·  Verified Buyer  ·  12-01-2020  ·  LCD-GDW-Boats

Two power supplies

The model is convenient to use as it comes in the set with two power supplies - AC/DC power supply and a 12V power adaptor. So you can choose the one that suits you best.
Dear Oscar, thank you for the feedback. Your opinion is very important for us. Best regards, Support team.

 ·  Joe Rodriguez  ·  Verified Buyer  ·  11-01-2020  ·  NS-2000-Smart

Highly efficient model

This model of booster is my favorite one. It amplifies all types of signal for all operators. I won’t change it for any other! This is just what I have been looking for our building.
Dear Joe, we are glad to know that you are satisfied with the purchase. Best regards, Support team.

 ·  Rashid  ·  Verified Buyer  ·  10-01-2020  ·  NS-2500GW

Wide reception

That's great that the booster is able to cover with the signal the area of my place on the very floor and around the house. Earlier it was too hard to make uninterrupted calls from the attic or the basement.
Hi Rashid, thank you for the feedback. Thank you for choosing our company. Best regards, Support team.

 ·  Rosie Dean  ·  Verified Buyer  ·  10-01-2020  ·  NS-GDW-L-Boats

Perfect solution

This booster is a miracle! I bought it to amplify voice communication and 3G when I’m offshore and the device perfectly deals with these tasks. My husband and I have three yachts and we installed this amplifier on the largest one. We were surprised that even the fact that there were a few levels on the yachts didn’t impede the booster to do its work. Maybe some people will find the device a bit expensive, but it is definitely worth its money. We have been already thinking with my husband to equip the two other yachts with such devices, but I think we will choose those with a smaller coverage area this time.
Dear Rosie, thank you for the review. Feel free to contact us whenever you need. Best regards, Support team.

 ·  Rico Avellan  ·  Verified Buyer  ·  09-01-2020  ·  LCD-500GD

Great device at a competitive price!

The signal amplifier has saved the day! We couldn’t get any bars on the phones in our apartment. The batteries were constantly going dead trying to find a mobile signal. We now enjoy 4 solid bars.
Dear Rico, Good to know that we could help you. Best regards, Support team.

 ·  Alexander Black  ·  Verified Buyer  ·  09-01-2020  ·  NS-300GD

Free delivery

I've chosen this company because of free delivery which is carried out directly to a workplace or home. Besides, I've got a package after 4 days which is rather quickly.
Hi Alexander, thank you for the nice words. Look at other devices on our official website. Take care, Support team.

 ·  Tom Goodram  ·  Verified Buyer  ·  09-01-2020  ·  LCD-300GDW

Good triband booster

Nikrans LCD-300GDW model was released in 2018, so it’s so to say a ‘fresh’ booster. I installed it at home and the signal really became more stable. The voice communication is significantly better with the booster. The amplified signal is equally disseminated around the whole house thanks to the indoor antennas, two ceiling and one whip. The company provided three-year warranty and all the documents for the product. I think it’s worth buying.
Dear Tom, thank you for the review. We would be glad to see you at our store again. Kindest regards, Support team.

 ·  Brian Anderson  ·  Verified Buyer  ·  09-01-2020  ·  NS-5000GDW

Short сoaxial cables

Everything was good, but the cables in the kit were too short. It was impossible to connect the outdoor antenna to the booster box. I had to order an additional cable, a longer one.
Dear Brian, thank you for the feedback. Please, feel free to contact us whenever you need. Kindest regards, Support team.

 ·  Amber Anderson  ·  Verified Buyer  ·  08-01-2020  ·  NS-5000GW

Short cables

The booster isn’t bad. It really improves poor reception. But the content of the standard kit upset me a lot. The length of the cables which came in the set together with the indoor and outdoor antennas was surprising. The indoor antenna had a 5m cable, and the outdoor one had a 10m cable. It’s strange! Just because the indoor coverage is so vast! So as you can guess, I had to order additional cables to install the device.
Dear Amber, thank you for the feedback. Please, feel free to contact us in case you need help. Kindest regards, Support team.

 ·  My grandfather is happy  ·  Verified Buyer  ·  08-01-2020  ·  LCD-400D

Sammy Wise

I knew that my granddad was having signal issues in his cottage, so I decided to buy him a repeater as a surprise. He actually found out I was buying it, but he’s very happy with how good his signal is now!
Hi Sammy, it’s great to know that your grandfather is satisfied with his booster! Best regards, Support team.

 ·  Archie Ellington  ·  Verified Buyer  ·  08-01-2020  ·  NS-GD-Drive

Easy usage

I really admire that I could quickly install the repeater by myself. It fulfills all the promised functions with a simple set of components for a car – a cable, two antennas, and a 9V power supply working from a cigar lighter. The mobile signal increased to 4 bars and I can make reliable Skype calls even outside the town after switching on the engine.
Dear Archie, thank you for choosing our company. Best wishes, Support team.

 ·  Bonnie Bernard  ·  Verified Buyer  ·  08-01-2020  ·  LCD250-GSM+4G

Didn’t need to change the operator

My signal troubles were so annoying that I was thinking of breaking up the contract with my operator. Turns out it wasn’t their fault, and a signal amplifier helped me out with everything. The solution was much easier than I thought though the delivery was a bit long.
Hi Bonnie, it’s good to hear that your problems are solved so easily! Sincerely, Support team.

 ·  Kevin  ·  Verified Buyer  ·  08-01-2020  ·  NS-GD-Boats-L

Easy to use

I have a booster at home, so I knew what the main working principle of this device is. But using a marine booster turned even to be easier than a home repeater. The components are the same – a booster box, two antennas and mountings with cables.
Dear Matilda, thank you for the review. We are happy to know that you are pleased with the purchase. Kindest regards, Support team.

 ·  Charles Smith  ·  Verified Buyer  ·  08-01-2020  ·  NS2500-GSM+4G-PRO

Good product

I am satisfied with this booster very much. It has everything I wanted – a huge coverage area, three working bands for improving voice connection, 4G internet and even 3G, and a good set of functions. I mean the shut-off option, automatic level control, manual and automatic gain control. The device ensured stable connection around the whole villa, even in the least covered areas. It is very compact and lightweight. I see no disadvantages of it!
Dear Charles, thank you for the review. We are glad to know that you are satisfied with the product. Kindest regards, Support team.

 ·  Patrick Clark  ·  Verified Buyer  ·  08-01-2020  ·  NS-1100GDW

Sophisticated installation

The installation of the booster seemed too complicated for me. When everything was connected the indicator became red for a few seconds and then it suddenly went off. I couldn’t do anything but call the support team. They explained that the reason was in strong input signals or self-oscillations. So they advised me to enlarge the distance between the indoor and outdoor antennas. When I did so, everything started to work.
Dear Patrick, thank you for the feedback. Feel free to contact us whenever you need. Kindest regards, Support team.

 ·  Louis W.  ·  Verified Buyer  ·  07-01-2020  ·  LCD1200-4G-PRO

Lack of manual

When I was delivered my model, I didn't find a manual inside a box. Perhaps, someone forgot to put it in. Luckily, someday I had an amplifier and could easily install and connect the components. By the way, it works amazing.

 ·  Marry Hutton  ·  Verified Buyer  ·  07-01-2020  ·  LCD-1200GD

Amazing signal at home

My husband and I bought a two-storey house in an outlying area of our city. We were so happy when we moved there. However, the next day showed that a phone signal inside the house was absolutely disastrous. We couldn’t properly either speak or work online. So, my husband’s brother told us about boosters. And we immediately found this one because it perfectly fits our requirements: a great coverage and what persuaded us - a 30-day returning policy. So we decided to risk. Today I honestly can say that we still use it and don’t complain about a poor signal at home. We also recommend buying this model to our friends who had a similar occasion.
Dear Marry! Thank you so much for the review. We are happy to help our customers constantly. Kind regards, Support Team.

 ·  Fabian Francis  ·  Verified Buyer  ·  07-01-2020  ·  NS-300-Smart

Very convenient

I used to hate the signal inside my family house. I often needed to go upstairs and just sit on the stairs while talking on the phone, because I had nowhere else to sit and it was the only place with a decent signal. But when I finally ordered a signal repeater, the entire family thanked me. Now we can all use our phones for anything we want in separate rooms. It works even in the barn outside. A great device!
Hi, Fabian! Thank you for this review. It’s good to know that our product helped you improve your signal that much. Best regards, Support team.

 ·  Archie T.  ·  Verified Buyer  ·  06-01-2020  ·  LCD-300

Pleasant to Work with

I would like to thank the managers working at the company. They are very polite, patient and careful. They helped me choose the suitable model of amplifier and explained how it is installed and how it works.
Dear Archie, thank you very much for your feedback and nice words. Hope to see you again. Best regards, Support team.

 ·  Sarah London  ·  Verified Buyer  ·  06-01-2020  ·  NS350-GSM+4G

Simple installation

I liked the product. It’s simple to install and the working principle is understandable. My husband carried out the installation himself. We had read the manual in advance, so we had no problems at all. There is a light indicator on the repeater, and when it turns on it means that the set up has been carried out correctly and without errors. No additional software was needed. It’s a plug-and-play device.
Dear Sarah, thank you for the review. Keep on enjoying the product. Kindest regards, Support team.

 ·  Edgar Tracey  ·  Verified Buyer  ·  06-01-2020  ·  NS-150

The functional one

I had a business trip and forgot to turn off the amplifier at home. I thought the bill would be enormous, but the automatic function of signal control saved lots of money. Great!
Dear Edgar, thank you for the feedback. We are happy that you are satisfied. Kind regards, Support team.

 ·  Mikhael M.  ·  Verified Buyer  ·  06-01-2020  ·  LCD-500GW

The device saved my business

Some months ago I opened my first 15-people office in the centre of the city for comfortable negotiating with the key business partners. Unfortunately, my lessee didn’t warn me about a poor horrible signal in a 12-storey building with metal and glass walls and our first working day was marred by this fact. Honestly, I didn’t know what I should do because we could hardly talk with customers on video calls. And I remembered that my old friend’s recently bought a booster for his house. I immediately called him and he told me about your website. So, I contact a specialist and in a 10-minute conversation, I chose the LCD-500GW model which was delivered after a couple of days with a full kit of necessary components. My deputy and I could install it within several hours without professional help and it works. Amazing!
Dear Mikhael! Thank you for your feedback. We are glad to know you are satisfied with our services. Best wishes, Support Team.

 ·  Lyla Luis  ·  Verified Buyer  ·  06-01-2020  ·  NS1100-GSM+4G-PRO

So good!

I will recommend this device to all my friends and colleagues because now I know that it is really effective and it really works. It improves even 4G and 3G in the warehouse where we had no mobile internet at all.

It’s not really good when phone signal and internet at your office is poor. That’s why we all were so happy after we got a signal repeater and installed it. The entire office can use it simultaneously!
Hi, Liya! We’re glad to know that everyone at your office likes the signal repeater that you got from our store! Best regards, Support team.

No lightning protection

There was no lightning protection in the standard kit. And for me this was a question of safety, so I ordered it additionally. The booster is okay.

Great for bars

I'm the owner of a bar in the building with thick stone walls in the basement. Last month a purchased this model because I'm tired of listening to complaints from customers about the poor reception of at least 3g Internet as well as about how it's difficult to make a phone call staying in the bar. I googled and found this repeater the delivery of which was organized for three days. Moreover, it was delivered to my bar and the installation process took only several hours. Then, I amused that the signal was improved not only inside the place, but it was covered the entrance as well. And there is one more thing I like. The amplifier's work doesn't greatly affect the amounts of payments in monthly bills.
Hi Ken, thank you for the review. We are happy you could solve your problems with a signal. Best wishes, Support team.

Found a scratch

When I was delivered an amplifier, I carefully looked at the device. Unfortunately, I found about a 7 cm scratch in a hard place to see. It's probably a manufacturing defect and I contacted the specialist. After thousand of apologies and 4 days, I got my excellent booster which operates absolutely awesome.
Dear Harriet, thank you for the review! We are sorry for the situation and hope that it will not reflect our future cooperation. Best wishes, Support team.

 ·  Josef Villeneuve  ·  Verified Buyer  ·  04-01-2020  ·  LCD-800

Gave me signal coverage

I live in a very remote location with no measurable cell signal on the smartphone. I installed the amplifier and was able to boost the minimal signal that was there so I can now make and receive phone calls.
Dear Josef, we appreciate your review. Thanks and regards, Support team.

 ·  Laura Stephens  ·  Verified Buyer  ·  04-01-2020  ·  NS-GSM-Drive

Quick delivery

I was going to another city to visit my friend and thought about a repeater too late. I read in the order form that free delivery takes 3-7 business days. However, I had to start my vacation after 2 days. I knew it was my fault I didn’t think about purchasing in advance. So, I decided to contact the service team to arrange the delivery in 2 days. Anyway, I was so happy when they could make an exception and I had a new model NS-GSM-Drive the day after. It was very important for me and I am so grateful for this kind gesture.
Dear Laura, thank you for the feedback. We are ready to help you at any time. Best regards, Support team.

Nice Booster

Nikrans LCD-130 is simple but effective at the same time. I’m using Vodafone and my wife likes O2 more, nevertheless the repeater perfectly boosts signal for both of us as it operates at a standard 900 MHz frequency.

 ·  Jessica Ashton  ·  Verified Buyer  ·  04-01-2020  ·  LCD-500GD

Does what it’s supposed to

It’s not easy to get signal while on water, and if we do catch some of it, it’s frustratingly weak. Things changed when we bought this repeater for our boat. It seems that it really catches the weak signal wherever it can and amplifies it. So yeah, it works! Both cell phone signal and 4G internet work so much better, and everyone noticed that. Now we don’t have to worry about missing any important news from the land while we’re here.
Hello Rufus! It’s great that you have such stable signal now. Thank you very much for your positive feedback! Best regards, Support team.

 ·  Joseph Blare  ·  Verified Buyer  ·  04-01-2020  ·  LCD1200-4G-D

That's pretty good

When I ordered this model I got it after several days which is too fast. When I unpacked the delivery box, everything was fine, all the components are in place. After unwrapping the package of a booster box, I found a little scratch in the left corner of an amplifier. Of course, the scratch hasn't influenced the basic function of the amplifier and my home signal I adorable.
Hi Joseph! Thank you for the honest feedback. Probably, it was a simple manufactory defect. We hope it doesn't impact our cooperation. Best regards, Support team.

 ·  Tiana Meza  ·  Verified Buyer  ·  04-01-2020  ·  NS200-GSM+4G

Works well for me

Needed a booster for my workshop with a metal roof. This one works really well despite the fact that I put the outer antenna not even on the roof or a pole but on the outside wall. The roof isn’t a problem anymore.
Hi, Tiana! We’re glad that everything worked out so well for you! Thank you for purchasing our product. Best regards, Support team.

 ·  Adam Page  ·  Verified Buyer  ·  03-01-2020  ·  NS-150GD

Not perfect

Well, the mobile booster isn’t bad in general, but still it’s not perfect. The coverage area is small, about 150 m2. My house is a bit more, about 170 m2. So when I’m near the indoor antenna which spreads the improved signal, everything is great, but if I go too far the signal starts to disappear. Perhaps, I need to change the booster model for another one, with a larger coverage capacity.
Dear Adam, thank you for the review. Feel free to contact us in case you need to change the model. Kindest regards, Support team.

 ·  Bruce Rakerd  ·  Verified Buyer  ·  03-01-2020  ·  NS-1100GD

Works well

Well I did a bunch of research and read a bunch of reviews. That really helped. I live in rural Sheffield. I didn’t want to switch carriers. So I am on O2, and I simply installed the outdoor antenna in the attic of the house, close to the bottom side of the roof. I have a 2 story house, so in general the antenna is high off the ground.Then I installed the indoor antenna on the 1st floor close to the ceiling. Now I have pretty decent signal in the house.Overall, I had basically 1-2 bars outside. Inside was like 0-1 bar. After installing this unit I now have 4-5 bars in the house. So it does work, and it seems to be working well. You just need to find the best location for signal to boost and repeat.Distance is the key to the unit working properly. Distance from the antennae is crucial.
Dear Bruce, thank you for the feedback, we greatly appreciate it. Kind regards, Support team.

A safe model

I bought LCD250-4G-PRO for my flat half a year ago and I have to say that this model is totally comfortable for using. In addition, I placed it in my room because there was the best position. And I don’t have any problems with my health. Even my girlfriend who can’t sleep with any noise pointed out that the booster is absolutely quiet. And I am not afraid it would be broken because your company provides a 3-year guarantee and service. I am totally thrilled by this repeater and I really appreciate how it effectively works. Amazing!

 ·  Julia Watson  ·  Verified Buyer  ·  03-01-2020  ·  NS-600GW

Difficult installation

Although everyone says that the booster is easy to install, for me the installation was a real quiz. First, my husband mounted the outdoor antenna outside the window and we see no result. Then we called the support team and they explained that the device would improve coverage only on condition that it catches an adequate signal from the nearest base station. So when my husband changed the located of the outdoor antenna and put it on the roof, it picked up signal and we got improved coverage.
Dear Julia, thank you for the review. Feel free to contact us whenever you need. Kindest regards, Support team.

Great solution

When I was in the sea I suffered from constant signal losses. Actually, signal problems weren’t new to me. I faced signal issues at home and I knew that the best thing to do was to install a signal repeater as at home but only for boats. This was my first marine booster and I’m satisfied with the result. The signal on board has become much more stable. Voice connection as well as 3G is without problems.
Dear Patrick, thank you for the review. We are glad to know that you are satisfied with the result. Kindest regards, Support team.
