As Rip Trippers promoted, this thing is a flavor bomb. Innovative design, no ramp up time, never tasted so much flavor out of my liquids (and I tried a lot of RDAs)
Only 2 cons are: max. 2 draws before you have to sqounk again. Better to squonk every draw. And the airholes are so tiny you can't see which you close with the cap. So you have to allign the cap before you put it on. Small cons, amazing device. Ordering one for a friend now.
