“This is a very good looking dual timer / dimmer. The dimmer section uses a green LED to indicate the set dim level (the LED is half brightness when off and full brightness when on). The timer portion uses a red LED to indicate the selected duration. When the timer is on, the red LED indicates the time remaining. Both switches use your previously set dimming / timer setting when the button is tapped. In all, a great product. I use mine to control bathroom lights and a shower fan.”
