The Dovpo Blotto V1.5 RTA is a rebuildable tank atomizer. The Dovpo Blotto V1.5 RTA features a dual diffusion airflow system, so that air flows through the honeycomb holes insides the posts evenly, which will result in efficient wire & cotton heating during work. Blotto V1.5 also utilizes stainless steel to seal the honey-combed style posts in the process of diffusion, which is targeted at heat resistance. The built deck allows you to physically wrap the coil, affix it to the system, then add a wick to ensure the flavorful vapor. The reliable top refilling design is easy to twist to refill, you can push it back and twist it again to install. It measures 26mm and has a larger 3.5ml capacity to hold more e-liquid, it is user-friendly for RBA beginners. Compared to the other sub-ohm tanks, it can save you a good duck due to its rebuildable design for flexibly experimenting with the coil for your flavor needs, on the other hand, you should empty your tank and clean it absolutely to change the flavor.
