I have used the product, now three times (3 cans each time) in the last month. I was notably impressed with the lack of smell the first two times. However, yesterday did not provide the results I had recalled. Let me clearly state that the smell yesterday was far less than the smell from another product sold on here. I had planned to provide a 5 star rating, but the smell experienced yesterday plainly reminded me of the drawbacks to gel-fuel. Hats off to Sun-jel for the continued product improvement. I have ordered this product at least 3 times over the last few years. Overall, I see notable improvement in the odor! As for the heat, well, it's not wood nor a larger gas log, but sure reduces central heat usage on cold days/nights! The appearance, crackling, and enjoyment of the fire are not diminished by the odor. Comparably speaking, I had some of the other product on here left over from last year. I burned three of the cans recently - great heat, excellent appearance, nice sound, but significantly greater odor. I have noticed the greater the odor, the more sinus issues I have. I plan to wipe out the inside of the firebox before the next usage and see if that improves the odor. Maybe the black buildup is reacting with the new flames? If I notice a difference, I will try to update, if possible. Overall, I would recommend this product.
