I contacted eleaf US. First they asked where I bought it. Then they wanted a pic of the scratch off code on the box. Then they said they couldn't help me. They said I needed to contact the supplier to the website where I purchased it from.
So I contacted the the owner of the website where I purchased the istick 50..... evape.us and asked for his supplier info like eleaf directed me to. He told me not to worry about it. He's gonna replace it for me. So a new one is on it's way to me.
In the meantime, I ordered a new eVic VT to replace the iStick 50 as my go-to regulated device.
evape.us has proven to be a stellar vendor...
