This is an awesome device, I love it for when I’m away from home. It’s super tiny with great flavor and no leaks.
I’d suggest trying to suck juice out to see if that works. Maybe there is a clog in the line and that will flush it out. Drip some juice in the ada so it has something to suck. Beyond that I’d say just get a refund or swap. Best of luck to you.
Oh and just a heads up ejuices dot com has the kit for $41 and the two packs of ada’s For $6. In case you get a refund and what to get it somewhere else. Assuming you didn’t get it cheaper of course.
