Yankee Candles are crap. Cheap, wax based product that smell like a gas station bathroom. They don't burn cleanly and don't last long. You will end up repainting your ceiling if you use them often.
Spend a little more and buy a nice soy based candle like Voluspa. Sure, it costs more but the scents are clean and luxurious.
cheap product and cheap quality
I keep an extra box of these for my tart burner. They work great but I've found them cheaper at Bed Bath and Beyond.
