This product is falsely advertised, because it doesnt burn for 3 hours maybe an hour and fifteen minutes, also the flame height is only approximately 4 inches tall barely visible behind the firelog. One last thing some of these cans have deep dents is it safe to burn or will the heat cause the dents to melt or open. I compared this product with Real Flame gel and the real flame burned for almost three hours with a very visible flame.
