One thing that people really want is to protect their dab rigs from the heat of their torch while they're heating the quartz nail. The rotating arm of this piece is perfect for exactly that function. You can rotate the arm up and out of the bulb to heat it without any fear of damaging the rest of the rig, and then you only need to rotate the arm back into the bulb for instant vaporizing action.
With the addition the carb cap, this piece is sure to provide you with the ultimate vaping experience. You won't lose any of your vapor to the surrounding air, and you can use less heat since the cap protects against slower hits evaporating away. Cleaning and upkeep is easy with this piece since it's made from quartz. The dish will burn away residue when heated to a white-hot shine, and the rest of the piece can be cleaned with warm water and a bit of scrubbing action.
