I can't believe you're even asking this question lol.. The
smok TFV4 produces about as much clouds as any drippers around and produces WAY more clouds than the Zephyrus. I've used both and you really can't even compare the two.. The TFV4 blows it out of the water in terms of cloud production. In terms of the
tank the TFV4 will put out more clouds than any other sub-ohm
tank on the market. It's in a league of its own.
