I ordered six candles. Two are already not working--apparently my new batteries can't maintain the contact point for the candle bulb to stay lit... unless I turn the candle upside down. LoL. I'm also unhappy with the timer, which is promoted as a very vague "dusk 'til dawn." How many hours is that? Who knows? And do all the candles turn off and on at the same time? I still can't say, as I haven't been able to catch them turning off. I had better luck with a set of 8  candlesI bought on the cheap from a local grocery aisle six years ago. Disappointed.
