Have used the first time the candles this year. Easy to use with no tangles - super! One click - the lit candles! Cheap the whole thing is not - but stress-free. What I did not realize was that the candles but are considerably darker than the one I had always otherwise. For a tree with a height of 2.30m I had 1Basisset and 3 extension sets. That was not enough to me. For the next Christmas I bought another 2 extension kits additionally. The batteries have with a burning time of about 8 hours daily problems endured 14 days -.. And were now just half empty during removal.
