https://www.vaporrange.com/asMODus-C4-BF-RDA-p/asmodus-c4-rda.htm The C4 RDA by asMODus is an all new flavor oriented, single coil rebuildable dripping atomizer that utilizes a unique airflow system which consists of fully adjustable, dual 9-point sloped inlets. The idea behind this system is that it causes airflow to evenly enter the RDA at an angle from both sides to create an internal cyclone airflow system. This tornado effect airflow provides ample vapor production and impressive flavor which is directly injected via the angled 9-point inlets. The C4 RDA build deck is constructed from high quality stainless steel and is 24K gold plated for maximized conductivity. The top cap is constructed from 6063 Aluminium which is hard anodized for a premium finish. The C4 is amazingly low profile for its efficiency and offers a multitude of great features to make this a truly versatile, feature heavy RDA. The top cap locks into place via rivets on the deck to allow for easy airflow adjustments without the risk of removing the cap. The cap still retains the ability to be easily removed from the build deck by simply pulling up on it. The actual build deck of the C4 was crafted to be an advanced system with an easy to build deck. The deck accommodates single coil builds and offers beveled edges going through the middle of the RDA to allow a screwdriver / building tool to be set in place and drastically aid the building process. By using a tool and letting it lay down on these bevels allows for perfect coil placement. Coils are secured in place via vertically set hex screws which tightens wires down into place. The deck even offers a cut off section of the deck walls which allows to easy snipping of wires. The juice well presents itself in a slightly outwards-sloped shape which was implemented to provide even juice distribution. The C4 has the ability to easily change between squonk (bottom feeding) and standard usage and utilizes a split 510 pin which symmetrically dispenses juice into your wick and not upwards toward the user.
