About this device
The G Pen Roam is a concentrates device built around water filtration: a borosilicate glass Hydro-Tube sits inside the body, giving genuinely cool, smooth vapour without needing a separate rig. A quartz tank and long vapour path handle the heat, with temperature adjustable from 600 to 800F in 25-degree steps for dosing control. The 1300mAh battery gives up to around 20 sessions, heats up in about 30 seconds, and is swappable for longer days. For a UK patient prescribed concentrates who wants the smoothness of water filtration in a portable, the Roam is a clever, self-contained option. One-year warranty.
