I would argue that the first 10 seconds are not all air. According to the instructions of the volcano, it says wait 3 seconds. When I use mine I usually will press the air button and then put the bag on right after(within 1.5 seconds). If the bowl is big enough I will see vapor filling the bag instantly.

An improvement that I think could be made to the volcano is:

- put lights on the red and green button on the digital volcano, so you can see them in the dark.

-the red button is stupid. they should make it a black switch. its confusing to other people that aren't familiar with the vape.(they tend to think that red means stop and green means go) and its not like you have any reason to hit that one button except for twice every sess (once to turn it on and once to turn it off) [contrast: i like the green button]
