I got it from vapedojo and the coupon code is sxmini. I heard it while watching plumes of hazards live show last night and raced over to see if it was real. And to my amazement it was, I've seen deals for the ml for 159$ or so but none that were that low. And yeah I know the firmware won't work from the m class to this I'm just asking if updating is bringing anything great to the table? I don't really need to make custom screens or anything. I would like to adjust the power curve feature where you can adjust the power delivery but I don't need it now. I just wanted to make sure there weren't any bugs that firmware fixed or any good improvements. As long as it's basically the same as the m class with a few benefits I'll be a happy camper.
