Yes. Dot Aio is not regulated...more of a mosfet/potentiometer device. Okay for some, but my OhmVape (Dot Aio clone) went back in the box.

For higher resistance builds that many Billet rbas require, the ability to control your wattage is huge, and the DNA60 is a very powerful low wattage chip.

The Boro mods with Sevo 70 chipsets are no slouch either.
