When the cigar arrived, I wasn't sure what to do. It came without any instructions. After another quick call to customer service, I was informed that I just had to remove the white rubber plug in the end, and start puffing.
At first I was disappointed. It seemed only like water vapor. There was plenty of it, but there wasn't any flavor beyond that. I brought it with when I drove to and from work, and continued to evaluate it. At some point the second or third day of trying I tasted the flavor! The flavor did remind me of tobacco! There was plenty of vapor, and the mix of the flavor did resemble a cigar.
I got called into work after hours one Saturday, and I decided to do a comparison. I smoked a real cigar on the drive to work, and the Cohita D1500 on the way home. I really enjoyed both. I would compare the difference between them to the difference between a Diet Coke and a regular Coke. They resemble each other, but you can tell the difference. And you can get used to it if you want to make the jump.
I'm starting to lose vapor at this point. There is still plenty of flavor, but I'm lacking vapor, so the experience is less satisfying. I also don't think I'm anywhere near 1500 puffs. The end still lights up, and there is still some vapor, but not near as when I first started on this disposable electronic cigar.
I've enjoyed this enough that I'm probably going to make the jump to a re-usable/re-chargeable electronic cigar. I would recommend trying a disposable to see what it's like before making the jump.
