I've been noticing this a lot and if you don't mind me asking, what does the firmware have to do with your vaping? The limit is in the PCB itself, it can come out with a billion different firmwares at the end of the day your vape is going to be the same as it was at version 1.0... I've been looking at some reviews and unless something's changed, the firmware is kindof pointless, it doesn't add anything to the quality of your vape, merely gives you something else that you don't need... like a vape profile... totally missing the point... firmware does not determine vape quality, which is what you want when you get a device right?
