I previously owned a buddha and I experienced the same problem with the low heating. I actually emailed customer service about it and they said the reason the heat of the vaporizer at 12oclock may be equal to another vaporizer at 3oclock is because of the height of the ceramic heater. look at your buddha and see whether the ceramic stick is towards the top of the glass piece or lower down. The higher it is, the hotter it will get.:thumbsup:
