A tri-coil RDA? Yes please! Hellvape has stepped the game up and released a tri-coil RDA for those cloud chuckers and flavor chasers! While you can fit three coils, you can also use this deck for a myriad of configurations including dual coil setups! Plus the airflow customizations on the SERI are top tier allowing you to dial in your perfect vape. Plus a 6ml deep juice well allows for maximum squonk or drip action!
