These are OK window candle lights. I wish I'd paid attention to how unattractive they are during the day. The most prominent thing seen during the day is the respectively huge solar panel. It is definitely not pretty to look at! At night they are pretty points of light in the windows. The suction cups hold well and you can remove the unit easily without having to remove the suction cups themselves, by using a handy latch mechanism. One of the two that came in the set is not as reliable and doesn't seem to charge all of the time therefore stays dark at night sometimes. I really hate it when only one lights up as they are in the two windows at the front of my house. It just looks sloppy! Things to keep in mind when shopping for window candles.
