My adult daughter loves andything that sparkles, shines or lights up.  She teaches dance classes for kids at the YMCA- and the kids notice what she wears, especially if it is sparkly or 'princess-y"  She was thrilled to get the is watch as one of her stocking stuffers for Christmas and kept showing everyone (and even posted a video of it on facebook!)  I don't know how long it will last, but for the price it's already been worth it for the fun.
