Congrevape's Ignition RDA is the latest evolution of the very popular DOGE RDA. This rebuildable dripping atomizer (RDA) measures 22mm in diameter and features a comfortable 18mm build deck holding a dual post set up. The positive post and large surface flathead screws are manufactured out of C110 Food Grade copper, offering superior conductivity. The laser cut airflow holes are large and are embellished with a distinctive design. And like the DOGE, this RDA is topped off with a wide bore ceramic drip tip which promises to stay cool to the touch. A truly excellent bit of vaping gear.
