I have 2 of them. I have not had positive results yet. I initially attached them to a evod battery, but couldn't get the vapor volume and flavor that I was used to from the evod
tank. I purchased 2 itaste v3.0 batteries, hoping that this would solve my problem. Still had an issue with poor vapor production. IMO, the evod
tank is much tighter than the mini protank 3. I finally gave up on the mini protank 3, switching back to the evod
tank on the itaste battery. I blamed the problem on the dual coils and small battery, which may not be true. I just ordered a couple of mini protank 2's. Once they show up, I will let you know if I have any better results with those.
