Magic Tricks

The promotion piece has an error - "Your hand is empty the whole time!" The device has to be in either hand the whole time. Also, there is no PDF with the package. You must go to the QR code on the package. The password is printed below the QR code. The instruction video does not provide instruction on how to have the next sound to be the one you want. There are several nice sounds, including Happy Birthday. But there is no explanation as to how to have the next sound to be Happy Birthday. You have to push the button multiple times to find a specific sound. You can't do that while you have a table full of guests intently watching your presentation.
Please have someone provide the instructions.
