It's only the most technologically advanced PV to date, by far. Completely computer controlled, programmable feed system (touch to manually feed, or simultaneous feed/fire with customizable flow rate), touch driven interface with "buttons" like your touch screen cell phone, juice scavenging (no more juice leaks or wasted juice), built in USB passthrough/charger, boost circuitry gives the same vape regardless of battery charge level, pump draws next to no power meaning it won't negatively effect battery life... the list goes on and on, but I've got to head out the door to work before it gets any later.
When it comes to PV's, different strokes for different folks, but frankly this thing is impressive as hell.
