Sorry, but I was a little disappointed in this product this time - - because I believe these were old cans. I have ordered this producet many times, from you as well as other vendors and have never encountered MOLD around the top rim and inside cap of the cans. The burn was okay, but gave off a funny smell n the beginning. Then I noticed the usual smell of the ethenol. Also, it could have been my imagination - - but I could swear that they did not burn the normal 3 hours. At one point in time, I remember saying, "Is that one going out already?" it was a little weird that a can of Ethnol gel could grow mold and how did it grow? So this time around I have to give you low scores on this product. Maybe I should order them from someone else.
