Jensen Real Flame is a good fuel gel with about a 2 and a half hour burn time. It produces about a six inch flame which is just right for my fireplace.
I searched around for a great price and great customer service, and i found it at Northline. The price is excellent for the Gel Cans. found these on other websites for 50% more. The product burns great and you really get the feeling of a real fireplace without the mess. There is a little bit of a smell if you use the product in a room that is not well ventilated. For my use, it's perfect. The cans burn for the stated time and it's easy clean up.
Will be purchasing more cans from Northline just because of the great price and excellent customer service.
We love this particular gel for our gel fireplace. it emits a lovely flame & if you burn two it really warms up our room!!!
