The AMPUS Screwless Two Post 25mm RDA by AMPUS has a revolutionary screwless, two post build deck with spring loaded terminals alongside dual adjustable side and bottom airflow capability. The spring loaded terminals have a clamping space of 3mm by 2.5mm and the 7mm deep juice well allows for more E-Juice to be retained within the atomizer. Airflow enters the AMPUS Screwless RDA via two types: the side lightening bolt shaped airslots (special edition has ohm shaped side airslots) allow airflow in through the side, while bottom vortex 45 degree airflow allows airflow to enter at the bottom and be redirected below the coils. Both types of airflow capability can be fully closed for user versatility. A 10mm wide bore 810 drip tip is included with the AMPUS Screwless RDA and can be of either delrin or acrylic material (chosen at random). The AMPUS Screwless Two Post 25mm RDA is a unique rebuildable dripping atomizer with high performance capabilities.
