Before, when you had micro usb and upgradeable firmware, Pico 75, etc, there was a forum that made software for Pico 75, which made the Pico very good in TC, not as good as DNA, but still a big upgrade from Eleaf's TC.
You make the Pico 75 again but with USB-C and non-upgrade firmware, a bit like going backwards into the future.
Maybe you at Eleaf should consider making the chipsets upgradeable firmware for the future, so that you get us older people to buy Eleaf again.
