SMOK NOVO 4 is the latest in one of the most loved series of vapes in vaping history, the NOVO. It's slightly bigger than its previous version but that's for a good reason, the introduction of a new airflow control ring, means that the SMOK NOVO 4 is the first to have any kind of airflow adjustability. Another new feature is that it has replaceable coils, each coil has 3 silicone rings which SMOK claims, provide a leakproof experience. The NOVO 4 uses a new LP1 coil family, with a 0.8 Ohm LP1 Meshed coil (best at 12W) included in the kit, for a soft and mellow flavor.
