After I was very skeptical about the Flackerverhalten (there are plenty of different reviews for this purpose), I ordered these candles 4 weeks before. I am very satisfied, the flicker is really unobtrusive and - although all 3 candles next to each other - can in no way be of "Disco" is mentioned. Meanwhile I am so excited that I have ordered another set, so that I can fit my picture frames so. One thing I have yet to find fault, therefore only 4 stars: the 2 brightness levels are barely distinguishable. But I do not really not that important. Therefore, I recommend the product you.
