Pro Easy to use scheduling
The scheduling feature is easy to use - select a time to turn on, and a time to turn off. You can repeat this schedule (called a 'rule' within the app) daily, or weekly.
There is also a built-in timer, which can be useful when you only need the lights on for a few minutes during an irregular time.
Pro Well designed app
The app is designed to look sleek, and give quick access to commonly used actions. Finding a specific device can be a hassle if you have many HomeKit devices connected in the same room as the lists scroll vertically, but this won't be an issue for the vast majority of users.
Con No third party ecosystem integration
Unfortunately, it seems this plug isn't compatible with WeMo, Nest, SmartThings, Wink, or other home automation ecosystems. This limits the devices that this switch can connect with in the future (or the present if you already have non-HomeKit devices).
