Review on Wi-Fi signal amplifier (repeater) Wi-Fi Amplifier PRO, black by Mateusz Strach ᠌

Greatly enhanced the signal of an expensive wifi router. At a distance of twenty meters, there was no signal because it had to pass perpendicularly through three concrete walls that carried loads. The setup took 3 minutes (roaming is turned on with one button), I installed it 5 meters from the router (through 2 walls), and here is the speedtest: the router has 20 Mbps, at the farthest end (where there was no signal at all) - 10 Mbps . Wonderful! Prior to that, I had a lot of trouble configuring routers to work in repeater mode, and nothing I tried worked. This thing was activated, tested, and then forgotten.
