Just put this out in my garden this week and it is very cold outside. Seems to be doing well. It gets dark here from around 6pm (sunsets at 5) and the light comes on until about 4am.
What you can't tell from this product photo, the inside of the moon is made of a kind of polished brass. It's very reflective at night a quite lovely. When spring rolls around, I will be pairing this in my garden with rosemary or lavender.
I don't know what the other reviews are talking about when they comment on how small it is. It was just about the size I expected, as a solar light enthusiasts. It was about 5 inches shorter than I suspected. But still very lovely.
I give this 4 out of 5 only because the glass ball doesn't sit flush with the base. But it isn't noticeable visually.
