The voice control setup was way easier than I expected—just a few taps in the app and my Alexa picked it up right away. I’ve got it on my coffee maker with a morning schedule, and the 8-timer limit is plenty for my weekly routine. Feels solid and the ETL cert gives me peace of mind leaving it plugge

The energy monitoring is a game-changer—seeing exactly what my old fridge pulls per day helped me rearrange schedules. Setup took maybe two minutes, and the ETL certification gave me peace of mind plugging in my coffee maker. Voice control via my existing assistant works flawlessly every time.

I’ve been using it to schedule my coffee maker every morning and the 8 timers are plenty for my routine. The energy monitoring is surprisingly detailed, and the whole thing feels sturdy out of the box.
