I bought the first incarnation of the DaVinci last year and found it to be much different from the competition. First of all, the heating time was much shorter with my original DaVinci and the all important clean-up is even simpler than I could imagine. Although I don’t use the first incarnation of the DaVinci any longer (I now use the newest version, the IQ2). The IQ2 makes the job of vaporizing my medicinal herbs a true pleasure. The flavor from the newer IQ2 is full and robust and it is never harsh, nor is it ever hot on my tongue.
