GreenSound was found by a Korean professional electronic engineer Kim Long in 2008. Employing more than 500 staffs, GreenSound is now operating in a factory area of 10,000 square meters equipped with LEAN production lines that qualified with dust-free requirement. Consistently abides by the ISO9001 Quality Management System standards, strictly controls every operation procedure from research to manufacturing and it has obtained various international certifications such as European (RoHS, CE) and American (UL, FCC) certifications.
The GS-H2 is a bottom coil clearomizer BCC (so no long wicks), which means better flavour, faster flow of e-liquid, and therefore larger vapour production. It utilises a standard 510 threading so it's perfect for any 510 threaded battery you want to use it with. Unlike the CE4/CE5 the mouthpiece is not separate and the tank is filled from the bottom.
