Below, we find the on / off button that slides below. We can not do more basic. There is also a small hatch for access to the battery, CR 2032, one of the most common formats (batteries for watches, heart rate monitors, kitchen scales ...). Once worn, we can thus easily be replaced. On the qualitative side, I will not go so far as to say that it is mistaken because it is really the plastic base and do not confuse it with wax. The flame is it much more lively and a white candle light. Small fluctuations in the light of the led are welcome to approach against the illusion of a flame. It lights against a little less than a candle and dazzles more. If it is fixed in the dark, it's embarrassing limit. A timer function is announced (from the fact startup) per 24-hour cycle with 6 hours walking and 18 hours of rest before resuming. I do not see much interest unless you want daily candles lit at the same times on a time range of about 6 hours (as complicated niche!).
In short, there is here a good value with candles sold less than 1 unit to the very long life thanks to efficient LED technology for energy and deemed the very long lifespan. Despite the somewhat cheap, we could be tempted if the fire phobia. This is ideal, however in the evening with the advantage candles without the drawbacks. I recommend!
