…but seems strange that happens only when it have 2ml of juice, your one wick good till the last drop? maybe I got a fault one!
I will let you know if solved with less cotton!
Thank you

I tested the juice volume with 2 different brand Cabeo’s and they both ran nearly all of the juice. It sounds like the capillary action is not working right in your tank, a mechanical problem: something blocking the tube, the capillary tube plate is not sitting flat against the bottom, perhaps an o-ring, a piece of cotton? Or a fault like a wider or uneven capillary tube, a bent tube, a bent raiser plate etc. You may also want to watch a YouTube review too. Sometimes the reviewers who communicate with the manufacturers, indicate useful things about the tank assembly or coil build that may cause problems.
