How to tell when the vaporizer is cashed?

It turns a dark brown color..I recommend getting a bobbypin and stretch it open so it looks like this: ______________________ and use it to stir the weed that's in the bowl for the vaporizor. I can get better hits that way and I can catch it usually before that nasty "burnt popcorn" taste as referred to above hits my lips (thank God! iccccckky!)

And my friends, take it from me, don't smoke the remains of the vaporizor bowl in the bong. It is absoultely disgusting. Not only does it give you the nastiest aftertaste the smoke smells like dog crap. Bleeeeeahh!!

I love the vape, I always "hit the floor" I kneel when I hit it.. gotta make that shit whistle!

Love the vaporizers!
At first I would hit my vape like 3 days in a row and think "there's no way this weed can still get me high" so I would change it up But now I hit it till no vapor comes off.
GREATEST INVENTION EVER!

Which is your favourite?

i have a vaporbros.. and like they guy before me said, when it tastes funky like burnt popcorn, its done. also I put like .2 in my vape and it lastes a good 10 minutes... half a gram lasts about half an hour give or take 10 min depending on the weed...only takes me one .2 gram bowl to get a good buzz, 2 to get HIGH

before the burnt popcorn taste. i stir mine, when all the color is leached i dump it. i always use hydro so the color change is very noticable, if using dirt weed the color may stay close to original. use a stir stick & hit it SLOW for second hits. i like using a reg. bong now w/heatgun. easier to control the heat when you can see whats happening. tripp
