So relaxed attaching the candles on the tree has never been. No cables that must be taken into account and to switch on and off, there is a practical remote control. The AA batteries will last the Anzen holidays, although the candles are turned on with us at least 10 hours per day. The light is also very pleasant. Not Siehnt like Xenon light on the car, but has a yellowish tint. I ordered two of them and that the tree is well stocked.
