Popped over to Bangkok for a couple of days earlier this week. Took my travel setup: Vaper Shark rDNA40, Youde Bellus RTA, and 30ml of DIY Unflavoured. No issues with customs, and while I didn't see even one other vaper, no one battered an eyelid as I vaped in public. The rDNA40 I bought specifically as a travel Mod is a bit of a pain. The magnetic battery cover fell off repeatedly. Once in my bag, once as I removed it from my jeans pocket, and twice just in my hand as I vaped. Not idea but worked well enough.
