...for my 'Vaporesso Gen Nano'. Just keep em at 40.0 and the smoke is mellow and tasty. At the lowest pwr setting you will find the coils get the best life cycle. Just NEVER puff on an empty or low tank level. Once you take that burnt "plasic cotton wick" hit even once your breathing will worsen and coils burn out fast.
If you start to get the yuk taste, before it goes dry, just put in an new coil then boil the yukky one vigorously while stirring for 5to10mins and it will remove most of the yuk so you reuse an old dirty coil.
