We even operate the radio Gong as an extension of our doorbell in order to hear the doorbell in the garden and distant areas. The range is reliable and perfectly, even when testing purposes behind our neighboring semi-detached house! Helpful is the adjustable radio frequency to possibly avoid "false positives" (joined us yet once). The discounter batteries last far more than a year. We have also clamped a second radio jingle for another house easily to the existing doorbell parallel. Highly Recommended.
