Re: How long does a vortex bowl last?
As you can probably guess, your session length is proportional to the way you smoke and the tobacco you use.
Smoke harder, get a shorter session.
Smoke poorer tobaccos, shorter session.
if you are getting it only to increase you session time, then don't get it.
The bowl should be used only for juicy tobaccos that would normally leak down your stem. Its fine to use it on dryer tobaccos, but you really wouldn't know the difference blindfolded.
