Button or auto switch? I haven’t used an auto switch in a long time. If you’re willing to go button only my favorite
mod to date is a vandyvape pulse2 squonker. It comes with an ok
rda. I got mine for something like50 to 60US + shipping. The screw threads for the bottle looked fragile so I’m careful not to cross thread. I don’t know if they actually ARE fragile, if I’m wrong it’s still fine.
