This product was a great idea and I am currently using it for holiday time. I guess it could be used for any time of the year. I love the fact that it uses solar energy but I believe there is a battery there as well. The connection or the suction cups that enable the candle unit to stick to the window is really not great and needs to be adjusted every so often as it loosens and falls away from the window. If the connection or suction cups to the window were a bit more secure, I think this product would be great. But for holiday purposes it really is very nice.￼
