Once I got it to stop leaking it's actually a pretty nice vape. I notice in the photo from Gatok that it looks like the air holes are in the base shown as it appears there is some cotton sticking out. I have the top with oval holes so tell me how do you get the cotton out of the holes once you put the top cap on...maybe I'm missing something. I too think maybe the oval holes are too big. I have three more of these coming so will see if all are the same. For now I'll just keep stuffing the chamber with cotton.
