Serpent SMM 24mm RTA with a redirected bottom airflow system, two post single coil build deck, top fill capability, and 4ml juice capacity. The Serpent SMM features a unique redirected airflow system which brings air in from a dual adjustable bottom airflow control ring, and redirects the air up into the posts of the build deck where it exits parallel with the coil. This airflow system helps reduce leakage in comparison with traditional bottom airflow and offers enhanced flavor production. The build deck on the Serpent SMM RTAis a two post design with two slotted terminals per post to allow coil mounting for both forward and reverse wrapped coils. The Serpent SMM also features a gold plated 510 contact, an ULTEM 510 drip tip, and a threaded top fill system for easy filling.
