Don't know what you mean by "pure". Vapor quality, as far as included toxins, is a matter of temperature, not model. The DBV, being a full sized whip model, naturally gives bigger hits than the narrow bowl on the Vapor allows. You could argue that the Vapo (used properly) is more efficient though, since really big hits are kind of wasteful.
vapefiend Reviewed by vapefiend on . Vaporizer recommendations Although portability is not all that important to me, if there is no downside, I wouldn't mind using a portable at home. The Volcano is way too expensive, especially as I could buy an iolite and an SSV for less money. I've never used a vaporizer of any kind before, but after 35 years of smoking, I'm kind of tired of the nasty taste from smoking, so the concept appeals to me. I really can't spend more than 300.00USD, so it comes down to either a launch box and 'da Buddha (best of both worlds?), Rating: 5
