What issues have they had? I had some issues in the very beginning with my puffco pro but I've had my Puffco+ since Monday and I have a friend with one as well with no issues. But there may be bad batches. My last experience with them over issues was handled 110%. They were a little slow reply to my messages though but they followed through on every promise they made and even gave me a free extra pen and extra coils to make up for the slow reply.
