I had a Punch Elites EMS yesterday and things were well until the last 1/3rd when I started to taste an unpleasant change. I persevered for a bit longer and then gave up. I then cut the end off and saw that it had started to burn only in the core and had not been burning the outer wrapper. Does this happen much? Can I do anything to prevent this? I guess for a cigar under $4 I can not expect too much.
