I just bought my first Mod recently. I have an Eleaf Istick 60 Watt with a Herakles tank. I'm having issues with this tank leaking. Anybody out there have long term experience with this particular device and tanks in general that could help me stop this tank from leaking or suggest a better 100% leak - proof tank that is compatible with this device? I welcome any eliquid suggestions as well. I usually go with stuff from Halo and have been generally satisfied with their liquids. I also use liquids from Vista Vapors strictly for their low prices but haven't found an all day vape yet. Thanks a bunch and vape on my fellow vapers!
