The Citadel RDA is a 22mm rebuildable atomiser featuring a uniquely designed ultem chamber reducer and dual sided slotted post. The design allows for coils to be installed in any direction with ease. This RDA offers a familiar styled airflow from some of Psyclone RDA’s previous products but with a twist. The Citadel RDA is sure to impress, offering phenomenal flavour and vapour packed into a small package.
