My user manual states one minute shutoff, it does stay in Fahrenheit each time I turn on, I read in an earlier post that if you wanted Fahrenheit you had to reset every time. I have been getting pretty blown away and maybe the two minutes feel like one minute......
Received mine from VapeWorld yesterday, sn MY016934, one minute shut off is fine with me, very powerful!!! Before the mighty I was using the Pinnacle Pro, what a difference, well worth the investment.
