I bought 2 of the same birthday card and have only used one so far. I followed all of the directions as four of us screamed a birthday song, then mailed the card inside a package. When it arrived, the sound wouldn’t play but it only made an awkward noise. That was disappointing. The non stop feature worked as promised, with a pitiful little noise and then my sister beat it into submission so the glitter was not dispersed. All in all a disappointing experience for the price paid. Not sure if I want to even bother to use the second one.
