I have flown domestically and not encountered any problems at all with mechanical mods, batteries, etc from TSA. Has anyone gone through Canadian customs without any problems with their vapor gear? I'm somewhat hesitant to bring a mod only to have it confiscated. I was just thinking of bringing an ego to hold me over for a week but of course I'd rather have a mod. I haven't flown internationally in over 10 years and am completely unfamiliar with the process now. Any tips would be greatly appreciated!
