First off, let me say I am using a VaporDoc, a nice vaporizer available for around 180 on ebay or google it or whatever. I get WAY higher. It takes a week or two to get used to the differences between a bong and a vape. For instance, your lungs dont seem to fill with anything, because its not harsh like smoke. So it 'feels' like you are not inhaling enough. The taste is much more pure, so pure, to people just starting it tastes like burnt plant matter. Once you get used to the taste though, you'll never want to smoke out of a bong- funny how that works! I tend to go through the same amount of buds.. umm.. cant think of anything else really. Heres a pic of the one I have:
Ive tried the Volcano too, it's the nicest one out there- that is why its 500 smackers. I think the vapordoc is second, vriptech third and the rest mostly suck.
