Amazing little device

Really impressed with these, I bought a bundle of them and have buried them behind TV's, monitors, chargers, my home work desk - using the R5 scene controller it really has made this a super addition.
Verbal commands via Alexa, button presses on the R5, use of the app, it allows you to cut the power to standby devices and really see the savings when the electricity bill comes round.

Can't recommend these enough
