I used these on the fence around my butterfly garden.lasted about 2 years in the elements- I live in an area with harsh winters; very pretty, delicate looking lights.Took awhile to figure out that in order to change the mode of flash/no flash, the lights need to be on, meaning after dusk. Now instead of sporadic flashing and fading, the lights do a slow fade and are much more pleasing to look at. So far, so good.For me I need the item to look as good in the daytime as it does when it's lit up at night. I also think it would be easy to paint the wings with translucent glass paint on the wings to improve it for the daytime! I plan to do that myself?This was a gift that was received with delight!These are cheap and cheerful. The light quality is good, a soft orange. Unboxed them three weeks ago and hung them outside. They have been rained on and snowed on and had a few days below freezing - so far so good.Ordered the dragonflies this week.Days sun shines most of day they get a full charge and stay lit till the next morning. Very pleased. They are as bright as my electric lights.These are perfect for out door patio decoration and they don’t run up your bill.I put these on 5 wreaths on my front porch and it looks so festive without running electrical wires!
