After using this device for a couple of month, I think that I could have bought something cheaper. The booster is okay but as for me, it is rather overpriced.

Full kit and a very good manual. High price.

Excellent repeater for improving mobile internet! It is very convenient that when you order a device, you get a full kit. However, in my case, I had to customize my order and buy a longer cable. Thank you, Daniel, for paying my attention to this fact. Guys, if you are reading my comment and are planning to buy a booster, also pay attention to the length of cables that will be suitable in your case.

It’s the first device of this kind that I’ve seen in my life and I am very surprised that it can be so helpful. At our underground floor all the offices suffered from poor LTE connection. And we all decided to buy this amplifier.

This booster is a good solution for our supermarket. The signal used to be so low that it was impossible even to send a message in the app. That’s great that the improved signal doesn’t get worse when more people with their smartphones come to the zone of booster coverage.
