The device works fine, and it's easy to set up. The app is easy to use, but there are some odd choices. Why do you have to set up a "family"? Just list the devices.
Also, the app collects too much information. Why does it want to know your fine-grained location? Name? Phone number? Email? It's a glorified light switch! What's next, an extension cord that requires a blood sample? No-thank-you.
The device itself should not be Internet connected. You don't need to reprogram an outlet timer away from home.
The software on the device won't get updated, particularly when the manufacturer disappears. So you will become the unwittingly component of a botnet down the road when security holes are inevitably uncovered.
Smart devices are a Trojan Horse for planned obsolescence. They'll magically stop working or "will no longer be supported" and you'll have to buy a new one.
A much dumber device will be a better and safer experience.
