This was a first for me. I lit a really tasty cigar, but the draw was terrible. I could tell there was a really good taste underlying what I was getting, which was mostly air. After taken both bands off, I spotted an almost perfectly round hole on one side, you can see it the picture above. The hole was hidden under one of the bands, though I’ll guess this wasn’t intentional. Covering it up with a finger made everything good, though my finger did get a bit hot. Thought I’d share in case someone else has a similar, initially perplexing situation.
