Firstly this candle smells amazing, but is quite strong so I suggest you use in a large room...I've got mine in my living room. I like the size and design of the jar and so far the candle has been burning evenly with no tunneling...hopefully have a straight jar with no curves will prevent any tunneling. As the scent is quite strong, I only have this on for a couple of hours and it leaves a lingering scent in my room. Overall I'm impressed with this candle and would definitely buy in another scent.
