The custom scenes in the app are what sold me—I've got it set to drop the heat in the living room when I leave for work, and it's done it flawlessly every day. Setup was genuinely quick, and the valve feels solid once it's snapped onto the radiator.

Swapped out our old valve in under two minutes and the Wi-Fi connection was seamless. Being able to tweak the heat from my phone while at work has already cut our evening cold spots.

The app lets me adjust each radiator from my phone, which is perfect for when I'm already in bed and realize the hallway is freezing. Only gripe is the Wi-Fi setup felt a bit finicky at first, but once it connected I haven't had a single drop.
