I have a nearly new one for sale. It has a 4ml tank, uses an 18650 2500mah battery, has a MTL spiral mouth tip and a DL wide open tip. Lights can be customized or turned off at will. It uses a 0.5 ohm direct to lung coil or a 0.6 ohm mouth to lung coil. I also have 4 DL 0.5 ohm coils in unopened packages. I have no 0.6 coils. This machine spit back a lot for me but if you're not a furious vaper like me you may have more luck. The unit was $29.99 + $13 for the battery. The two extra coils cost about $8. I'll sell it for $25 and I keep the battery or $35 battery included.
