"I suppose you might be able to buy some specialty candles that are better than these, but I doubt it. I burn A LOT of candles, and I pretty much have a candle burning perpetually in my home. These burn a long time. I havent looked to see if it is really 30 hours, but i think it probably is. The Hawaiian, Brazillian Acai, Cranberries and Frost, and Fresh Linen are all great and today I am trying the Fresh Spring. The scent is so much better/stonger than others. My only complaint is that I would like to see more scents that are non-food related (i dont like my room smelling like a cupcake) and I would also like to see greater availability at a more consistient price. Walmart wants about $6 for one and Kroger wants about $10...but really these are better than any other candle I have found."
