This works exactly how it says and how you would want it to. Very good product
My internet was always shutting down because of sketchy service but since I got the unit it hasn’t shut down at all. I am so glad I took the chance and bought this very booster.
This is an excellent signal booster. I have used it for approximately three months now, and the results have been fantastic so far.
It is like I am near a cell tower. Great device.
This amplifier does exactly what I hoped that it would.
