One Yocan fan has purchased a UNI Pro last week and all the buttons stuck a little bit. A few days later they were totally stuck and would not press down at all making the vape unusable.

So, how to fix the Yocan UNI Pro Button Issue.

First of all, please check the button still click or not. If so, please try to tap it lightly.

Or the button can't click any more, you need to contact the head shop you bought it from to claim the warranty.
