Provari
Pros:
- Well built. I've been using mine for more than 2 years now.
- Always available (you don't have to stalk their website everytime just to order one.)
- Top notch protections.
Cons:
- Not a VW.
- The display is getting old.
- Current limit 3.5A. Nowadays people needs more for running multiple coils.
Dna20
Pros:
- Very versatile VW. Easy to use.
- Very informative display
- Comes in many shapes and form.
Cons:
- You will have to wait to get one.
- Too powerful for some people.
- No voltage setting. (For using multiple coils) I still prefer my zmax for dual / quad coils.
This is just my opinion, my personal preferences, might or might not be suitable for you.
The cheapest Dna20 mod I've seen is by Dz nutz (jcmsvapes), just Google it.
