Vivant Dabox Pro

The Vivant Dabox Pro is a concentrate pen with a full-metal body and a borosilicate glass mouthpiece that doubles as a small bubbler — so the vapor is drawn through a little water and arrives cooler than from a bare pen. Heating is via a quartz coil built as a swing-out replaceable unit: you fold it out to the side for loading. Three of these coils are included, and more can be bought. An LED screen selects the heat setting. At around 11 centimeters of body length and roughly 13 by 8 by 8 centimeters as a kit, the Dabox Pro stays a handheld that fits a pocket. Vivant gives a two-year warranty. The maker does not state a specific battery capacity or charging method — in practice what matters is that the swing-out coils ease loading and the glass bubbler mouthpiece makes the draw smoother.
