I found this quiet interesting MTL RTA. Here`s the link: Gotank mtl RTA - Fumytech $27.18 Authentic Fumytech Gotank MTL RTA Rebuildable Tank Atomizer - 3ml / 22mm diameter at FastTech - Worldwide Free Shipping I see the top cap is threading like Berserker MTL RTA. The deck is GTA style with Merlin Mini Style which the cotton will drop into a slot. The look is quiet sexy. And compact. The one is not clear is how big is the airflow channel and how tight the draw. I never had a Fumytech product, so I wonder anybody here has their product? How is the build quality of Fumytech product?
