I'll confess to a certain fondness for TC Vaping - and I certainly don't get a flat boring vape - I get a consistent flavourful vape, wicks that last for weeks and coils that last so long I can't remember when I made them. As for overpriced Evolv - Ha, give it a rest Scrumpers old bean - £45 for an SMY DNA75 That is massively customisable or £99 for a YiHi M class that barely manages to have memory slots...
Oh and on DNA's you can change between 8 profiles and select different materials, temps and wattages that are stored automatically all without going near a computer, but then unlike YiHi you've got a computer interface that allows you to customise screens, battery profiles, TCR, TCR Curves, led outputs, error messages, buttons, and more besides, you can log second by second firing data, resistance data, battery pack or individual cell voltage data, total power, puffs, mean power, puff, puff durations etc, etc, etc...
I understand your attempt to preach the gospel of YiHi but The FSM bids us "Think For Yourself", So I'll sit here and think you've had one to many sherries again...
