Update After a bright, but cloudy day, the lights came on dim and only stayed on for 1 hour. Given that I wanted these for winter patio lighting in the Pacific Northwest, I’ll be returning them. Super disappointed. If you have direct sunlight all day, they’ll light up for a few hours, but anywhere with cloud cover doesn’t seem to be a good fit for these lights. 

Set up was easy and they are the perfect amount of light for our patio. I do wish that they came on a little earlier. It has to be very dark for them to light. Otherwise, I’m very happy. They seem rugged and we’re easy to hang.
