144-Hour Candle

A candle that burns for 144 hours, the wick end rotating as it pulls the coiled candle up from below, seems like a neat idea. Except:

1. Unattended flames (primarily candles) cause over 1/3 of the house fires in the USA annually.

2. According to one of the two reviews, the wax drips down onto the coil as soon as the candle burns a little bit, ruining the whole thing immediately.
