The gel flame works great.  It usually lasts about 4 to 5 hours per can and heats the living room and kitchen about 2 degrees warmer (we have a fire place that holds up to 3 but usually use 1).  Opening the cans could be a little easier as you have to pry it open and get it loose but still a great buy (doesnt take much effort, just use a regular knife or spoon and little effort).

The shipping from wayfair was also extremely fast even with standard shipping.  The product came was shipped within 14 hours of placing the order and got here fast.  I will be buying again
