My set up , davinci iq2 on a little bong, burn at around 400-410 you get cool clouds of vapour, i also have the davinci iqc in the uk which works just as good but costs less. Well worth the money in my opinion, being an ex smoker i didn`t want to go back to burning the herb, almost a year down the line using this setup now and no craving smoking and still able to jog 8k every morning
