Earlier today, I posted about my dissatisfaction with my Kanger Protank. After reading several other posts, I read one that stated it was his juice. Well I'm happy to report it was my juice also that was causing a funky metallic taste! It was the traditional menthol juice that I ordered from vape4life. I do like some of their juices, but sure enough when I smelled it, it had a odd odor. Just think, I have two other tanks coming in the mail and I was about to give up on them. Now, I just have to work with the "airy" flow. I've ordered some EVOD heads and a air tank controller, so me these will help. The air flow is annoying, but not a show stopper at this time. Thank you guys for this forum, it has really helped alot!
