Works great, a million times better than PWM controllers

Works great, a million times better than PWM controllers. Haven't used the advanced features yet, but everything works great so far. The only problem is the display. As others have said, the emoji is completely meaningless. Also, the same backlight on/off button is used to turn on/off the load. So if sometimes you just want to see what's going on, it turns off the load etc sporadically. If you plan on switching the load on frequently (not automatically), I would recommend connecting an external switch for your load.
