Great features but tricky installation
The device works great and the readings are accurate. However, installation wasn't straightforward for me since it requires some electrical knowledge. Once set up, it has been very reliable and useful.

Good value but Wi-Fi can drop
I like that it gives detailed power usage metrics and supports voice control. My only issue is occasional Wi-Fi dropouts, which can be annoying but don't happen often.
