This is an excellent and relatively economical solution that far surpasses the technology of extenders. We live in a detached house, which is built above a single-room basement apartment. Due to work, we wanted internet access on the lower floor as well, but the signal did not reach there. The two apartments share a common electricity meter, but have different electrical panels. However, the shared wiring created the conditions for the device to work. One unit is placed directly into a socket near the router, preferably with an ethernet cable, and the other directly into a socket on the lower floor. The connection between them is immediate and devices that require internet can connect wirelessly without any issues. As for losses, we have a 300 Mbps fiber optic line, and the device provides a maximum speed of up to 30 Mbps in the lower area. It is highly recommended if you wish to connect between floors.

It is easy to use and does its job well. Indeed, it should not be plugged into a power strip but directly into the socket because it greatly affects its performance. I haven't had any interruptions at all so far and even in the basement where I had very little signal, now I have 70Mbps; of course, inside the house I have 300, but it covers my needs.
