To light the candles just tilt the glass, same action to extinguish it, the autonomy of 24H is both simple and well designed, they come in many colors (red, blue, yellow) the low light nothing to do with a candle they are supposed to simulate a candle effect is against the guarantee, I think it's very convenient if you have small children (the candle does not mix well with banbins) or if you want to create just a small, intimate atmosphere friendly (bath, decorative table ...).
Goodies: autonomy (24H), induction charger, available colors, the quality of polished glass.
Cons: Low light (compared to a candle)
Conclusion: really interesting and practical product they create an intimate atmosphere while being decorative objects, personally I am fulfilled.
