This year I wanted to for the first time on real candles waivers and these battery candles've bought. My conclusion - the electronics is good. One battery charge lasts for less than a week - enough. The Music Remote Control shaft quickly and easily all the candles to use at the same time - that surprised me most - very good. The three lighting programs are very nice. But unfortunately the case, especially at the thread is extremely poorly finished. If the candle once down or you cant only once the thread is over and you can not really screw the cap - which you have to throw away the candle. This is in our one week where I happened to me the lights at the same use 4 candles. The base are in this case sometimes even apart. So idea is good, but when the case processing has to be done something. Therefore HANDS OFF !!!
