Don't let the looks of this device deceive you, it packs some serious punch! With the .25 ohm coil and huge 8.8ml liquid capacity, this is the perfect on the go device for sub-ohm vaping. I love my large expensive mods, but for a night out, going to work, etc., the value and performance of this little device can't be beat! Serious cloudage going on here. One minor gripe, the 0.6 ohm coil noted as "mouth to lung", is more like a slightly tighter direct lung vape given that the airflow is not adjustable. Still a stellar vape experience on both coils! Well done Joyetech!
