Customer Stories

I have understood that the company is serious

The bad signal in the house did not permit us even making a phone call. After getting a signal amplifier I got 4-5 bars with optimal coverage. The company is serious, with the professional team.

Giampietro Saragozza · Siracusa, Italia

Product: NS-550GDW

We are located in a rural area with a very weak signal.

With an installed signal amplifier we have noticed a significant signal improvement at our working sites. I send you some pictures to show the installation we've made.

I’m expecting some upgrade in business!!

We persuaded the boss to buy a cell phone repeater because it was almost impossible to work. Having called to your company we have made the decision. Now the connection is just perfect, such a pleasant surprise!

Customer Reviews*

(GB)  ·  Purchased Nikrans NS550GDW  ·  March 26, 2016

I would recommend this product simply for its price and coverage ratio. My old repeater has very poor range in my house, and I often had problems with gsm signal reception - that was really annoying!

Before I installed the Nikrans booster I read through the online FAQs on and the manual - the installation was ever easy! Besides, it is great to have a amplifier that finally works!

waited rather long for my package - but now that does not matter

I bought Nikrans NS550GDW amplifier from the company. I am totally satisfied with the customer service. My helpdesk agent was Ana S, who made a remarkable job. She was helpful, always wrote answers immediately. She was helpful with my issue of the payment too. I can just offer this company for amplifier services.

(UAE)  ·  Purchased Nikrans NS550GDW  ·  June 24, 2015

I will express myself in english because i am confortable that way, so I received the amplifier, i was skeptical in the beginning because i used different amps in the past with poor results but this one really works! I am really satisfied. I guess every amplifiers are not equal.
