I bought this because it looked great on the trailer.
And again after 5 years of "no purchasing
anything until I see it in front of me" I made the mistake and bought a product from watching the
video.
The idea is great as you can see on the trailer.
But the sound that is happening when
the gimmick is "working" is too loud.
Also you can't be close to your audience because from the
side they will see that something is "strange".
Another product ended in my drawer.
