I understand, I wouldn’t touch this either.
To this day, one of the cleanest tube mods, which is a bit of a copy of the Aspire CF Maxx 50w - 2015, is the monochromatic range of the Freemax Twister from 2019-2020. Built-in battery, mesh, double mesh coil, good flavor reproduction, and power adjustable with the ring at the bottom. It was also an excellent tube mod. As far as I know, they sold a lot of them.
