My problem is the absence of mobile network connection in our house. It has one floor and 4 rooms. I installed the booster in one of the rooms. The installation was simple. I did everything in 30 minutes though I'm not a technician. Watch the photos I made. You will see that the booster is compact. Its sound doesn´t disturb us at all.
Now I have the excellent network connection in all rooms of the house. And many thanks to the manager Julia! She replied to all my questions with politeness. She recommended me this great booster and helped with the payment. My family is happy to have a good connection. Thank you!!
