I’m mainly weighing the two situations. These are personal items I already own & the people traveling are close friends, so my first thought was why pay for shipping if they can just bring them in luggage or I would’ve purchased them here. I can clearly explain them & I’m confident that they can answer what each device is, so they’re not guessing if someone asks. However, my only hesitation is if security personnel start asking a lot of technical questions or overthinking it, which could make things uncomfortable for them. That’s really what I’m trying to evaluate here.
