This breaker is perfect for anyone who wants to save energy and lower their electricity bill. I can monitor my energy usage and turn off appliances when I'm not using them. So convenient

Michael P

I'm really happy with this wifi breaker. It's made my life so much easier and I love being able to control the power remotely. The app is user-friendly and the energy monitoring feature is a nice touch.

Sarah Johnson

This WiFi breaker is a game changer! I can control all my home appliances from my phone, even when I'm away. No more worrying if I left the oven on. Love it

Laura Martinez

I'm totally in love with this smart circuit breaker! It's super cool that I can control my electricity with my phone. The app was a breeze to use and the installation was easy peasy. Highly recommend it!

Juan Lopez

I wasn't too sure about getting a smart circuit breaker, but it's pretty sweet. I can check out how much energy I'm using and schedule appliances to turn off when I'm not home. And, being able to cut the power with my phone is a bonus safety feature.
