I've tried a few different scents of the Avon 3-wick candles. I'm pretty impress with the staying power of these scents. Some are stronger than others but they all make a mid-size room smell amazing! They burn pretty evenly but leave some wax at the bottom (this is a pet peeve of mine, why can't they keep burning until most of the was is gone?) These candle claim to have a 30 hour burn time. I haven't timed them but I think they come close but don't quite make it to 30. My best guess would be about 25. If you can find these on special then they are definitely worth it! My favourites are Salted Caramel and Dark Roast (which smells like a moka to me!) I will repurchase.
