Honestly for girls I have a really cute screen protecter and it has a glitter shimmer on it and it is really hard to scratch. But do you notice that other cheap ones tend to scratch easily? These don't.
The link above is the one I always buy and I've been using that company for 2 years just for my phone to be clear. I ordered my iPad mini screen protector from and ebayer in China. It took about 2-3 weeks.
Hope you find this useful. I don't have any scratches or bubbles on my protector and it was so cheap!!
