The Vandy Vape Pulse 22 BF RDA was designed in collaboration with Tony B. to create a unique 22mm diameter bottom feeding RDA for squonker devices. The Pulse RDA features a pre-installed squonker pin and also includes a 510 contact pin adapter so you can use the Pulse RDA like a dripper. The Pulse RDA features a postless build deck for single coil builds. The low profile design allows for easy and varied coil builds. The unique side airflow design blows air directly onto to your coil. The unique leak resistant quadruple airflow slots provides a great amount of vapor and flavor production. The adjustable airflow top cap features four airholes that may be adjusted down to your personal preferences.
