I'm posting this in the veterans forum because a lot of you use HV devices. Right now I'm using a Prodigy V3 with Ikenvape's HV 510 atty's. Apparently these do not go well with this device. (I emailed Isaac from Ikenvape about the issue and one of his first responses were 'You wouldn't be using a V3 would you?') There was a big draw issue on their 510's. After the first day they started failing... So now I'm looking for a new vendor that has good performing HV 510 atomizers that work well with the V3. Thanks!!!
