Hmm, thought I'd chime in on this, as I'd hate to see you waste money on the rubi and not be happy with that either. The rubi is pretty airy, by design. It has little holes on either side that increase air flow. Some people block it with their finger to customize the hit, but if you hit it straight it can feel really airy, which increases the amount of vapor but also produces a less intense hit, though the type and flavor of juice you use will affect that outcome as well. I use a lot of mint/menthol so it works for me just fine. I'd suggest though, with these things in mind, to try the smok infinix, another refillable pod system. I really enjoy the intensity of the throat hits, which are more pronounced than either juul or rubi. Way less expensive too. Don't get me wrong, I like them all for different reasons, and the rubi by design is the closest to juul, but the infinix isn't much bigger and has sleek in hand comfortability as well. Oh, and the infinix pods hold more juice than the rubi. Cheers!
