The Elf was the first truly concealable auto-draw cart battery and its one of the bestselling 510 thread batteries sold on VapeBatt.com. Because this is an inhale-activated device it is always on standby meaning that it is ready to vape when you are.  This small vape also has a vape cart viewing window so you can see how much oil is in it.  And, there is a carb hole on the bottom of the body.  Covering the carb hole in full or part allows you adjust the strength of the airflow when you inhale.  This is great when you have thicker oil that needs a little more puff power to get it to vaporize to your satisfaction.  The Honeystick Elf is a 510-thread cart battery that has maintained immense market popularity and is backed by their 90-day manufacturer warranty.
