I have been using my tp link plug for over an year.  I like it so much that I have added a single switch, dimmer switch, 3 way switch and 3 bulbs.  Clearly a big fan.  

What would make it even better is if the sunset option allowed you to add or subtract time.  For example turn the light on at sunset minus 30 minutes.  At sunset is already too dark to walk across the room.

Thanks to link for creating great products.  I'll be adding an outdoor plug this summer, keep the great products coming!
