The ideal setting on the extreme is 230 degrees Celsius. The temperature is measuring what is at the element temp. The slow you suck in the vapor, the more dense it is and man, I tell you what... it hits like a pro. I can understand the glass pieces not being under warranty cuz of all the clumsy ass ppl out there. I absolutely love this thing tho. Lemme know what the link is to your comparison thread! :thumbsup:
