Reports are mixed on connectivity and responsiveness, with some customers describing rapid on/off behavior, and reliability concerns include units reportedly failing after several years. Those experiences matter for a Wi-Fi-controlled switch intended for routine lighting. The aggregate rating is broadly positive, but does not establish performance in every wiring or network setup.
