Does exactly what it says. Setup was pretty simple using the Kasa app. I use this as a timer for garden lights, since the app makes it very easy for me to change the schedule, without getting off my arse. The old timer was one of those digital things with 10 buttons that made no sense, and once you lost the manual, it was essentially impossible to reprogram
This also connects to Google Home app, so you can control the power via voice commands, and you can configure more advanced triggers based on different conditions. So overall, this is a neat easy to install product.
