Session Odyssey

The Session Odyssey pushes vapour through its own body. The air path runs vertically inside the aluminium shell, so a dab loaded into the ceramic chamber on top leaves residue in the metal tube running through the middle of the device before it ever reaches the glass mouthpiece or the 14mm adapter at the bottom. The magnetic cap that sits directly over the chamber takes the worst of it.

1. Swab the chamber while it is warm: KandyPens' own answer for the Session coil is a Q-tip after use. The atomizer is all ceramic, a plate element rather than a wrapped coil with wicking, so a cotton swab lightly dampened with isopropyl can go straight over the chamber floor and walls with nothing to snag on.

2. Soaking is allowed, water is not: for a deeper clean KandyPens says to take the atomizer out of the device and submerge it in 90 percent isopropyl for five to ten minutes, then air dry it fully before refitting. The one hard rule is that water must never go into the Session coil.

3. Twist out the mouthpiece filter: the filter inside the magnetic glass mouthpiece clogs before anything else does. Grip its sides, turn it counter clockwise to free it, and soak it in 90 percent isopropyl as well.

4. Strip the body for a full clean: pull the 14mm glass adapter straight out of the base, it is held only by three clear o-rings, then lift the magnetic cap off, remove the atomizer and take out the metal air tube. Soak those small parts in alcohol, wipe them, and run a dry swab down the inside of the empty body. Do not pour alcohol into the shell itself.

5. Never fire it empty: there is no burn-off shortcut on this one. KandyPens warns that heating the ceramic coil with nothing on it sends it into thermal shock and cracks it. Load first, heat second, and if the material is used up before the 60 second sesh mode ends, double click to stop rather than let it run dry.

Most of the mess starts with overfilling. The instruction card asks for around 0.1g per session, about the size of a grain of rice, because the chamber needs airflow to breathe, and going past 0.2g floods it and sends oil down into the tube. The atomizer is a consumable on a proprietary, non 510 fitting, so keep a spare in the carry bag. A red flash usually means the device is not reading the atomizer, so reseat it and clean the connection before assuming the coil is dead. KandyPens' lifetime warranty covers the battery, not the atomizer.
