Hi, welcome to ECF and I have (briefly) seen voice control activations on some
mods. It's an interesting idea, not one I'm really into (I tend to talk out loud to myself from time to time, I don't consider voice activation a boon-- for me-- exactly and you will surely pay some sort of premium for being an early adopter of this new technology (which may or may not work out well).
However if it really interests you and you can afford it, I see no reason not to get it necessarily, especially if you think you'll find the voice function useful.... So, I see no reason
not to buy one, if you get what I'm saying.
Do report back if you do, and welcome to ECF and congratulations on switching to
vaping. Well done
Anna
