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.
I've had mine since Monday as well, and have run almost a gram thru it, almost exclusively at green heat setting.
I get barely a hint of vapor, unless on sesh mode at this heat, but since I'm a low temp ghost hit kind of guy, I don't view this as a problem really, getting very little visible vapor, as long as I get well medicated. Which I most certainly do, with say 7-8 ghost pulls on green heat holding down the button for 8 seconds each time.
However, after doing two sesh mode cycles at this light heat, the unit is very very warm, like in a suspicious way, compared to my Linx Hypnos, which never gets too hot ever, even after 8-10 hits, while holding the power button until the 15second long auto shutoff.
I wouldn't say green gets too hot to touch after 1 sesh cycle, but after 3 back to back sesh cycles it's very very very hot, where 99% of people wouldn't want to hold it and would set it down immediately, and ask if there is something wrong with it, and if it's safe...
The PUFFCO+ is much worse, heat wise, at the two higher temps, as little as two back to back sesh cycles on blue make it painfully hot, while back to back white heat sesh cycles make the unit DROPPABLY HOT. Like if you did a third or fourth one, with that much heat close to that much lithium, I wouldn't feel safe. It's hot enough where you would actually burn your finger if you held it.
I also loved the quick release mouthpiece since we all check out atomizers routinely, but after being active with it, and having it come undone in my pocket countless times, they need to have that "final snap" be more secure so I don't have my dart' rubbing oil into my clothes, and getting lint on it.
Also, airflow volume thru the atomizer could be greater, I really don't enjoy my lungs feeling negative pressure while pulling.
So despite all those complaints that have come with a week's constant use.... I feel this pen will still be truly great once they fix a few things.
1. Solve Heat transfer issue, whether it be an atomizer or battery terminal issue.
2. More secure snap in for quick release mouthpiece
3. More airflow volume, flowing thru atomizer.
4. Add an extra temp setting for 325-330
5. Raise atomizer airholes even higher on chamber walls
The heat issue didn't bother me as much when I just used it solo, Monday and Tuesday. But after I shared it with friends, and did multiple sesh mode hits, it started burning their fingers, to the point where no one wanted to hold it for fear of it literally exploding in their hand (that mod pocket guy with the burned leg really stigmatized vapes, and PUFFCO needs to remedy this heat transfer problem ASAP). Please remedy this dangerously hot atomizer/battery temp, ASAP, PUFFCO !
Make it happen guys !
