So I have a new Yocan Kodo vape and when I screw in the card rags all the way no smoke comes out but if I unscrew it a little it dosnt let me use it and the lights just blink every time I try using it


Answer:
Do you the ohm of your vape cartridges?
The Yocan Kodo is compatible with most vape cartridges that are >0.8ohm.

Please hold the fire button when you inhale.
If the battery flash 3 times means it wont detect the cart, try to use a q-tip to clean the contact point, or install a brand new one.
