The volcano is great, one of my favorite purchases ever. That said, anyone claiming it doesn't smell might have a skewed frame of reference. It won't stink up your apartment as bad as smoking for sure, but vaping flower absolutely smells like pot and it will be very noticeable if it's your daily driver and/or your landlord visits while you are using it. If it's just occasional use you may be fine but honestly this thing will become a daily driver. So fucking good. Makes pot last forever, even when my tolerance is high my wife and I can split a half gram and be sent to space.
Their portable dry vapes might be more up your alley. The Mighty is also excellent, but I haven't tried their smaller models.
It being illegal doesn't stop people from doing it.
