It says it's a limited edition ..seems a bit counter productive! It uses the same 1.5ohm coils that the standard Air uses.
It's not a sub ohm one though:
ELEAF will surprise you with the GS AIR - M, a clearomiseur not assets lacking!
Clearomiseur ELEAF GS AIR - M (GS19-M) is a larger version of the GS AIR (GS 16 PLUS) produced in series limited, equipped with a true ring air inlet (instead of a simple screw) setting and whose capacity has been increased to 3.5 ml. It uses the same resistors capable of operating up to 20 Watts (at 5.5 Volts). The quantity and the quality of generated steam is everything simply amazing. It fits perfectly on the battery-mod ELEAF IStick 20 Watts.
Strength DBC (bottom double coil) is large enough to support up to 20 Watts without any risk of burnt taste, liquid inlet ports are large enough to ensure a good nutrition liquid, even with liquids containing a high proportion of vegetable Glycerin, and perfect of its suction pipe centering precludes all risk of leakage or "glougloutage".
Its metal drip-tip is interchangeable, and its air flow is adjustable directly with its adjustment ring.
first use, it is important to let the resistance to soak properly liquid two minutes.
