I have recently purchased a yocan uni s universal portable mod to use for my wax and I'm having trouble figuring out if I should put the wax in the top of the diameter hole or not
The Yocan UNI S is designed for 510 thread oil vape cartridges.
Please do not load wax in the chamber.
If you want to vape concentrate, please have a glance at Yocan Armor Plus.
