Never had any prob w/ the red ones. I have tried 3 of the Emaralds and have a few more. The 1st one I smoked lit and burned perfectly but I could not get any smoke from it even though it was not plugged at all, the cherry would light up and everything but barely any smoke. The place I bought it from gave me another one. It smoked fantastic and I really enjoyed it. The 3rd one I had was exactly like the 1st. None of them tunneled on me though. I certainly wont be buying any more Emeralds.
ATuck and I actually met the lead rep of Miami cigar company when he was visiting in NYC, Rene. He assured us that the guarantee all their product and said there retailers do as well, so if you bring a complaint to where you bought them from they should replace them free of charge. If you have any issuess, PM me or Alan and we will get you his direct line and email.
