I've had them a few days now and so far so good...so good in fact I'm considering purchasing more. I placed 4 of the 5 candles outside around the patio, set to the timer setting. They come on as stated for 5 hours (every evening) at the same time, and yes they do flicker slightly; as a real candle might - which I didn't mind; to me it added a sense of realism. So with that, I'm a huge "evening ambiance" kinda gal, and put the other one in the house, bringing with it, its warm glow. LOVE the timer function - Yes I need more, and when you break down the cost per candle, it's a pretty good deal. I'll wait and see how many batteries they eat up, which if they do, well then maybe they won't get turned on as frequently.
