I love the idea of it, however it makes way too much noise!!! I don't ever write bad reviews. But if
you're going to spend $300+ on something than I think it's fair to know the downside. It makes like
a loud popping noise when the smoke is about to produce and the a whirring noise as it comes out.
But the noise is loud to the point that I can't cover it up with my voice. Maybe if there was loud
music you wouldn't hear anything but then they wouldn't hear my presentation either. But mainly the
issue with the noise is that it sounds like it's coming from a machine or device. So there is no
more effect, even if they don't know it's coming from the watch they'll still immediately know how
it works.
