The EHPro Zenith V2 is another fantastic RDA! It has 3 posts for dual coil builds, with adjustable airflow on either side. A brass outer ring can be rotated to adjust the amount of airflow. The top piece screws smoothly into the rest of the top cap, so you never have to worry about O-rings coming loose. What sets this RDA apart is the terminals; all 3 have wide slots, rather than holes, which provide better contact and reliability. The wide slots make it easier to build quad coils, parallel coils, or coils that use very thick wire. Leads are held in place with terminals that use allen screws, which means you won't have to deal with phillips-head scoring becoming stripped and unusable. The Zenith is perfect for anyone looking for great flavor and/or impressive clouds!
