My problem with it is the whole purpose of what the device does based on the post is stupid. It just puts a notification on the screen as a way to try and use social pressure to get people to stop vaping. But that doesn’t work cause no one really cares if you vape or not. Some people might even think it’s cool or might turn it into a game of trying to vape without setting it off to impress their other friends who vape. I graduated highschool in 2019 and people definitely vaped and the only people they really cared about hiding it from were the teachers, no other students cared at all. So because of all of that this kind of device is just a waste of money that could be better spent on educating kids on how vaping is bad, just like what we did for cigarettes that worked so well.
For listening with one pair of headphones I agree, but if I want to share audio with multiple people this is definitely gonna be better than using the splitters and have the audio be quieter.
