This product is the best one for the type of fireplaces that take alcohol-base fuel. I have ordered this product for years and it is great - crackles a lot - looks & sounds like a real wood fireplace. I just tried, for the first time, the Sunjel Crackling Alcohol fuel and was exremely disappointed. It is advertised as "crackling" - there was no crackling and it lasts only about half the time of the gel fuel. It was not worth the price. Jensen gel is the best value because it works the best and the burn time lasts twice as long, and also produces more heat.
I buy this stuff by the caseloads, it feels so good having a crackling fire on a cold night! I can't tell you how man people have thought it was a gas fire!
