I have a couple of Dracula pipes, and I enjoy them both; one is a bent XL apple and the other a straight billiard. My inner goth kid just adores them aesthetically. Same find them garish, but that is what is appealing to me about this line; the stems are particularly eye-catching.
As for how they smoke, well, they smoke roughly the same as any mid-grade pipe. The same materials and procedures that are used to make the Draculas are the same as most of the other lines in Peterson's lineup. I'm very happy with them. I never had any major QC issues with Peterson, and their bowl coating doesn't bother me.
I really appreciate how a lot of their lines are based off important works of Irish literature. I'm not a Hibernophile by any stretch, but I am a history and literature nerd, so it is really cool to see pipes devoted to trying to capture that spirit. The Dracula line in particular just makes the Halloween dork in me smile. I'll smoke a Dracula while watching horror movies in October as a kind of tradition.
