Bringing vape on a domestic flight?

I've got a vapor bro's vape and I would like to take it with me by plane. I was planning on cleaning it and throwing it in my checked in luggage. What do you think?

or would it be a better idea to mail it to a friend?

Shipping would probably be safer. Either way, clean it the best you can. Ideally, trash the tubing and buy a new piece. This type is easier to clean than some other designs, since your residue should all be in the whip.
