It was a pinnacle pro, I would heartily recommend that you do not use that vape, it has a number of dealbreaking issues and the service from the company has been far from satisfactory. The e-nano is a great one for that purpose, you did very well choosing that one my friend! That is probably the main vape that got me off smoking all those j's. I am a medical user and have very high dosage needs and there is no doubt you are right that I've saved my health plenty, especially after discovering concentrates! I recommend that all who have high usage requirements like me consider concentrates!
