Two post build deck for MTL builds. You can use flat/phillips screwdriver to tighten up screws. PEEK insulator around positive post. Φ1.5mm airflow hole In the center, and 2 wicking holes on two sides.
None diffusion airflow. Easy to adjust.
Improved Kayfun Lite style airflow. Adjust airflow from the side (you don’t have to unscrew the atty to adjust airflow). No airflow-ring, no diffusion, no worries about changing your favorite setting by accident.
Tiny Chamber. Decent flavor.
Diamond has small build deck, so the chamber diameter is small as well; Meanwhile, it features cone-shape bell. It has one of the smallest room inside for vaporizing.
