Works surprisingly well

I’ve been looking for a model to deal poor service at home and discovered this online shop. They advised me to take this model as it was powerful enough to cover both floors. I have 4 bars of GSM signal everywhere and 3 bars of 4G which is just perfect for me. So, yes, I'm glad with the purchase.

Dear Jacob, thank you for the review. We are glad that you liked our product. Best regards, Support team.

Fast delivery

The shipment took just a few days and the set included everything necessary for immediate installation. I have temporarily fixed it in the attic and it already helps. Now there are 3-4 bars in the house and no losses in service. Didn't hope it would really do something with poor 4G but it worked out. I'd recommend it.

Dear Nick, we are grateful to you for leaving a review. Keep on enjoying it! Best regards, Support team.

I was lucky with it

It took me from 1 bar to 3-4. The antenna is still set in the chair outside so have to fix it definitely to the house or on the roof. Works great, no complaints so far.

Dear Daniel, thank you for leaving a review. We would be glad to see you again. Best regards, Support team.

Ideal for Improving GSM and 4G

Actually, I needed it more for improving poor 4G, but it turned out that GSM signal becomes much stronger with the booster as well. I'm very pleased with this purchase and can recommend it to anyone looking for a booster

Dear James, thank you for the review. We are glad that you are satisfied with our product. Best regards, Support team.

Only for medium sized buildings

I bought it for my small hotel, but later found out that the coverage area is only 600m2, which wasn’t enough for me. So I changed it for a more powerful model which has a larger indoor coverage.

Dear Toby, thank you for the feedback. Next time you need a consultation don’t hesitate to contact us. Best regards, Support team.

 ·  C  ·  Verified Buyer  · 

Works with all British providers

I’ve bought it to improve poor reception inside my office. All my employees use different operators and, fortunately, this model is compatible with any British operator.

Dear Charles, thank you for the review. We are glad that the booster met your requirements. Best regards, Support team.

Good amplifier

Have chosen this amplifier as it boosts both voice connection and weak 4G. I’ve been using it for my office. Haven’t noticed any disadvantages yet. Good product!

Dear Steve, thank you for the review. Keep on enjoying it! Best regards, Support team.

 ·  J  ·  Verified Buyer  · 

Didn't put power supply

When I got my package didn't find a power supply inside. I contacted their support and they sent it to me but it took 4 days before I could finally connect my booster and check whther it was worth buying it. Have to admit that it works and the reception is stable on both floors.

Dear Joshua, thank you for the review. We are really sorry for this oversight. Best regards, Support team.

 ·  T  ·  Verified Buyer  · 

Highly reliable

In my opinion, this company offers the best ration of price and quality. The product is worth its money, it works without any problems and can be used for improving poor GSM as well as 4G simultaneously.

Dear Thomas, thank you for the feedback. We are glad that you are satisfied with the purchase. Best regards, Support team.

Ensures stable connection

The model ensures effective work of all mobile apps and stable GSM connection. It’s compatible with all operators (at least with those of our friends as well) and doesn’t occupy much space or overloaded with wires.

Dear Finn, thank you for leaving a review. Hope to see you at our store again. Best regards, support team.

Case Studies

Alan Simons, Burnley

Started working without delay.

After turning on the booster, all my family members were delighted to find out that everything was working very well and we now have a great signal in every room of our house, including the basement that we needed so much. And we all can use the internet for our every need, even if we all do it at the same time – the signal and internet speed is enough for all of us. We are very happy about it.

Amy Morel, Nottingham

Trustworhy and customer-oriented company.

I can say for sure that is a very reliable and trustworthy company. It helped us to solve EE signal problems in our countryside house. We liked the way managers consulted us any time we needed, providing detailed information concerning the models available, their working peculiarities and installation process. This is the best team of professionals I have ever met!

Yousef Hefti, Southend-on-Sea

Everyone is happy with the mobile connection in my café!

The booster which I have bought at is one of the best models available. It boosts signal in my café very effectively, so every visitor can benefit from a stable connection, without any interruptions and disconnections. The model is very stylish and it doesn’t spoil the design and décor of my café. What is more, the price is rather affordable.
