I took two to work in tandem with a Keenetic router. In total, three transmitters cover a one-story house of 145 meters with the Internet very confidently, plus it remains on a plot of 12.5 acres and next to it. Seamless wi-fi, convenient mobile application. Could be smaller in size, I think, but do not bother.
I included some photos to give a more complete picture of the experience.
