It gets two stars based off the app. If your thinking about buying this, download the app and play around with it. The app has a lot going on, may be useful if your integrating a bunch of stuff. But I just wanted to have a electric heater on a schedule and to easily turn it on/off at my convince. A Wemo smart plug is way better at this. Wemos app is much easier to use, as soon as you open the app, all devices are right there to easily turn on/off (amazons app is 2 clicks to get to the device). Scheduling is horrible on the amazon app, you have to set a time for it to come on and then set another timer for it to go off, with a bunch of unnecessary steps to go through (they should have a simple one page setup for this like Wemo). Otherwise the device does what it is supposed to do.
