I have never heard of it before, but I have used candles quite a bit including some of the beeswax ones that come in cans.
I like candles as easily stored sources of heat and light. I keep a few candle stubs in my emergency pack and camping gear for that as well as using them as fire starters.

I am not trying to offend here, but I have to ask this.
This candle seems a bit pricey, so what are the points about it that would justify the cost compared to other candles or lanterns?
