I've gone hiking and whatnot with mods, but here is the thing, it's the Bluetooth speaker I take issue with and honestly, I have never ONCE while mountain climbing wanted music to distract my attention, I am usually looking for the next place to put my hands and feet, and like, making sure no rattlesnakes are present (although I guess it might be fair to say, some judicious Taylor Swift here and there might scare away the wildlife, but I would definitely fall OFF the mountain and even with rope, that's just a never really truly enjoyable experience, either.
I don't think kids will want this. Serious teen vapers want to be ultra stealthy, and serious musical teens will take one look at that speaker and go, "Ugh." etc.
That's the problem with coupling unusual things together. Usually they both suck, and quality suffers, I mean, making a mod is HARD enough without trying to infuse it with "blue tooth speaker" capacity and waterproofness.
I'm also going to guess the waterproofness is seriously lacking, because anyone's gonna junk that mod long before the day it rains. I mean, I wouldn't buy it if it were "good" and it is so far from "good" that well, I don't think they're making it appealing to ANYONE frankly.
