Excellent!
I absolutely love these plugs! They work with Wi-Fi without having to worry about a 2.4 GHz connection like most other wireless plugs. The app is very user-friendly, and the scheduling features gave me peace of mind when I traveled across the country during the holidays. I love it so much that I even continued scheduling lamps to go off and on while I am home. Google home integration was also a breeze. Itâs also fun to play games on other people in the house by turning things off and on from another room.

Works great
I use for things that have cords with switches, easier than reaching behind chairs to flip a switch!

Great switch!
Would definitely recommend!The setup is vey smooth! Super easy to connect to Google home. I used it to control the lights in my living room and the timer is very convenient.The switch size is compatible enough to not block others.

Muy prácticos, muy sencilla la conexión con la aplicación y el uso de la misma es bastante amigable.Se pueden programar encendidos y apagados automáticos por horario (los que sean) y tiene tareas de retraso también.Los widget para Android son muy útiles para encenderlos o apagarlos a voluntad sin tener que abrir la aplicación.
