The first is the SDNA75 from SMY. It's a single 18650 mod made from zinc alloy and also has a magnetic battery door for easy battery replacement, although the mod can also be charged with its on-board USB port. Most of the unit is coated in a durable and grippy rubberized finish (or with a realistic hydro dipped wood graphic). A very cool device for a vapor who wants the control of a dna platform in a pocket friendly package
