I know this topic has probably been beaten like a dead horse, but here is my take on the volcano digit.
I have been vaping for many years now and have tried my share of vapes.
The volcano is no secret to anyone in the vape game.
It has been (and continues to be) the industry benchmark for desktop Vaporizers for some ~10 years, and with good reason!
It uses convection (hot air) to inflate a balloon with pure vapor, and then you inhale the vapor from the balloon at you leisure.
This allows you to walk around with the bag and easily pass it amongst friends, without being tethered to a wall outlet.
The flavour and efficiency is phenomenal.
It probably works best with the bottom screen filled, so I'm guestimating 0.15. Although I have been able to use it with smaller amounts very successful. But it really shines with larger amounts and is the ultimate group party vape. Sometimes I fill one bag whilst another is being passed around.
You always get consistent results every single time, which you certainly can't say for other Vaporizers. The volcano works perfectly every single time, no secret pack techniques or draw method.
For dry herb it can't be beat IMHO.
The quality of the device is second to none, some of my friends have owned their classic models for 6+ years! The EVO cloud is nice but there have been lots of issues with them reported and even my friends unit, so I didn't take the risk.
It truly is the Gold standard in my opinion
Have to agree with vape critic - Bud.. . 9.5/10
