I had problems with them at first: the wick burned almost to the end and the flame burst out. However, if you keep the bottles very full of oil, the wick will not burn out and you will end up with a large flame that any wind can handle. We used colored marble-like discs that my wife got from centerpieces or vases (I don't know where she gets these materials from, but I assume there were places for handicrafts and others). We filled the bottle a little over halfway with it and it's working great now. I took a star off the rating due to the learning curve and needing to read reviews to get it working well ;-) I was close to buying crystal balls but I don't need them now (or at least not yet ).
