They generally work well. I've had about six on/off smart switches and two smart dimmer switches for the last two years.
I use the Smart Life app on my Android smartphone to program them. I use them exclusively for lighting.
You can have a light go on 40 minutes before sunset and off at midnight, for example.
They automatically adjust for changing sunrise/sunset at your location and for DST.
And they automatically recover after a power outage...
That recovery from a power outage would be important. I don't recall returning from a 2 week outing without the timers being messed up from (even) momentary power glitches. YMMV
