Love these little candles! I purchased 10 of them in 2021 for my condo. Now that I’m in a house, I just ordered six more. They turn off when it is sunny and on when it gets dark. Check them the first few days as I noticed that one window wasn’t lighting, but it wasn’t the candle but the bright street light. I turned the candle so that the “eye” wasn’t facing the window and they worked great from there on out. I set them up on Thanksgiving weekend, and don’t need to touch them until January 6th when the decorations come down.
