Smokum. True I'm Canadian, and your American, but I won't hold it against you. 190 to 370. That true to. But do you really think that some think that cheap can give a accurate temp reading? The fact that like an anolog it is always on while you vape Sort of makes one wonder if the iolite can maintain a proper level of temperature cxontrol. What are the chances that the control has a 10% fluctuation range. Dry herbs are probably more forgiving than eliquid on the common mediums that we use. Another thing to think about. Where do the vent gases go when you are walking, and you have a head wind?
