Comes fully built and works well after you get comfortable with it. Don't overtighten the chamber onto the Puffco or you'll get red/white light errors until you untighten it a little; took half a star.

Lots of vapor, lots of flavor. Don't load big globs, stick w 1 or 2 large rice grains. The XL chamber gives bigger rips, but will toast your reclaim to the point it stops smelling good at all if you overload it with dabs.

Rebuilding the atomizer is fairly straight forward but you'll need tweezers. I don't like the soldered joints in the center and sensor wire leads of the heater, so I took a half star off. If you rebuild the thing multiple times, be careful with those jointed leads because the joint in the wire can snap if you twist it too much and then the lead might be too short to reassemble.

JcVap has been super responsive when I send them an email or live chat with them on their website. The individual parts are low cost as are the chambers themselves if you just want or need a replacement (especially through VgoodiEZ!).

JcVap support is very well informed--be nice to them and they will take care of you.

I honestly wouldn't purchase a 3DXL from Puffco after having used the JcVap XL version. The more important question I think is, "should I get a standard 5D chamber with a Ruby, SiC, or AlN insert instead?!" ...Maybe! But it's hard to say because they're both really great. The XL is better if you want to load bigger dabs at a get together, for example. But i think smaller dabs is better taste wise, so I also really like the 5D with inserts a LOT. Ceremic kind of has a taste profile you can get bored of.
