The idea with the receiver in the socket I find great. Flexible and save on batteries. Unfortunately, "sparking" the bell seemingly not even over 10m. The receiver is in a socket directly at the window, the bell not 10m away on the garden gate. Result? The bell rings, unfortunately, only every attempt 10x. If one imagines the bell directly under the window, it works. Unfortunately, less than 10m receives only 1 star.
