19 candles performed flawlessly, was unfortunately an irretrievably defective (a metal piece was missing). In each candle is a battery. The Duracell used by me each a battery lasted until after New Year's Eve, some were still not depleted the Abschmücken. The light can be easily adjusted via the remote control. With the continuous light liked better than the interval functions, but that is probably a matter of taste. Since the time until Christmas was no longer sufficient to replace the defective part, I kept the remaining 19. There is now a star deduction.
