I'm loving it, but still not sure how to properly use it. I do let it heat up for a minute, usually till second heat cycle. I get the flavor , but never really know when it's at it's peak. When u starte seeing like a white smoke when u exhale. Is that cuz is done? Do u inhale wile in the middle of the heating cycle? For how long you inhale? I usually turn it off after 15 minutes. Thanx!!
