i bought an electric vaporizor once for about$80 aus i thought it was shit takes to long to get any vapour ,couldnt get a good hit like a bong.
i did use a good one once but it cost about $2000 .it was called a volcano u loaded this thing up with your pot turn it on and it fills a bag full of vapour,a very white colour.then u undo it and suck the bag back flat,could get a good hit of that but still a different stoned effect i think it is something u have to get use to .
If u think the cheap vaporizors r good u should try the volcano..................
