When buying, pay attention to which version you take, with a European plug or ours, but in any case, both versions will work, and yes, of course, the signal will be the weaker the further the repeater is from the main router, but it will be better to catch it in this way you can increase your WiFi coverage by reducing its speed
I've added some pictures to my review to offer a more visual and descriptive account of my experience.
