I'm not sure vaping caffeine is a true delivery method. But the zero nicotine is what I wanted and the flavor is good.
It’s pretty good it just takes more effort to suck and to get the vapor out other than that it’s really good
not too strong and not too weak. pleasant flavors. I would suggest a chocolate flavor.
The strawberry ice caffeine diffuser has one of the best fruit flavors that I have had. I have tried the Baja berry and the pink lemonade but out of those two the strawberry ice has to be my favorite
