Temp control on the Smok M80 isn't real temp control unfortunately, the device fails the dry cotton test horribly.
Rather try the Evic VT, or the Heatvape Invader mini.

I have one and it's an awesome device. Seems to step the wattage up and down in temp mode trying to regulate the temperature but does NOT prevent dry hits.
As an 80W VW device it's brilliant though.
Waiting for my Heatvape Invader, very excited.
