I just got my Joye ego-t e-cig in the mail today and I am super happy. Just waiting on my e-liquid to get here. I hooked everything up and just did a little test vape, and to my surprise vapor was produced. The carts are empty so how did it produce vapor? UGH I am so stoked for my e-liquid... I bought 15 ml of vanilla 24mg and 30 ml of redbull 24 mg.
