I suffer from minor case of anxiety. Before I vaped, smoking caused panic attacks-- in short I was screwed. But since I started vaping I'm great and feeling much better.
Many questions:
Just peeled batteries, but there's a sticky residue on them. Should I clean them, if so with what?
2) the white circular paper on top came off, is this ok?
3) What are the plastic black casing for that come in the set?
