a post less 30mm RTA that pushes the envelope in RTA performance! The deck brings four 2.5mm x 3.0mm individual post holes for easy coil installation encompassed by a ULTEM insert that reduces the chamber and brings the airflow from the top to the side of the coils! True to all current VC atomizers - the Valkyrie does not miss the mark in the flavour department, however it brings ample room to fit a large variety of builds for all your vaping needs! If you were a fan of the Trilogy RTA - this is a MUST HAVE!
