I cant believe I didnt see any AroMed vaporizer remarks in here... I wouldnt do anything until u take a close look at the AroMed, I used to use the vapolution, i had to use a digital thermometer to determin my temps, and the vapir one forced air unit.. both of these for some strange reason made my breathing more constrict after i was finished and i couldnt figure it out. well to make a long story short, I have the AroMed and I have no restricted breathing when i am finished, I see another review of the valcano, also restricted breathing after.. i think its a mystery as to why there is breating restricted after using one of those vaporizers... I dont think it happens to everyone, just people with more sensative lungs i guess, and if u only have a small amount of money, then doods soldering iron for 50$ is better than wasting more money and it should still work just as good as the others, except with the 50$ deal, u have to sqweeze the trigger for a certain amount of time while others, u blindly set a reo-stat of some sort.. but if u want one that requires no personal tweeking so u can adjust to the vaporizer, only for all of those adjustments to completely dissapear in a different enviroment, like a friends house for example, and that is because different ambient temps, and slight voltage variations present at the electrical outlet, for example, ive been to house that only have about 105 vac, and others 120 strong..this voltage variation alone, not to mention voltage drops on the same circuit from other appliances kiking on or something else, will completely have u to be an ignoramous to your vaporizer... the deal is, plug it in one outlet, dont show your friends because u will screw up there vaporizing experience... if u want one that anyone can hit properly, then get the AroMed. No bull here
