I agree with everything that's being said about using a torch in public, how the Dynavap looks like a "crack pipe" etc.
I don't use these in public (well sometimes the Dynavap, in a shop doorway at night, you only need a small torch lighter for that). This is aided by UK law which forbids smoking in pubs, cafes etc. So outside each bar is a clot of people puffing away at Cigarettes, Ecigs, big vapes etc. Ideal camouflage once you're vaping
I'm simply putting forward my choice for vapes that provide instant (virtually) vapour, and don't continue to off gas your herb while you're not drawing.
Some people have said that torch vapes are dirty and smelly. this is simply not true, I've been puffing at my Sticky Brick for about a month, and all I've had to clean is the mouth tube, that gets residue in a sort of mist on the side, very hot water and a bottle brush, or iso wipe on the dowel poke through removes it instantly.
I can't undersatand why, but the vapour path, from the wooden bowl, doesn't get very sticky or gunky at all.
There is a stainless steel tube, about a inch and half long, which joins the bowl to the vapour chamber, that gets a minor residue buildup.
I gave it a full leisurely clean the other day, easy, and less than ten minutes.
Honestly folks I really urge you to try The Sticky Brick, or The Dynavap. They are effortless, and such a great taste, and there is nothing gucky about them.
As I said, I have a Firefly 2, I find it hard to draw, but I could't use it for stealth anyway, it looks like a drug piece.
I can easy get away with the Crafty and The IQ, and have done several times outside. My mates were singularly unimpressed with either of these, and mocked me for spending so much on things that didn't work that well.
Since then, a few have visited me at home, and they are all in love with both the Brick and the Dynavap.
Cheers all, John W
ps.
@LabPong, I've been looking seriously at the Elev8r, it looks great. A good idea for the heat source, I can see that irregular tip working well. It looks quality, and the little clip come stand. I thought it was quite expensive, and that, with my record with glass, wouldn't last long. So, I don't think I can get it in the UK yet, Namaste, and Vapefiend don't have it. As I say, it would be easy to break, and I tend to do that with glass :-)
I'd love to hear more about it though, so if you want to say some more about it, I'd love to hear more :-).
