NYX Cosmetics... Are they good?

NYX is surprisingly one of the best drugstore cosmetics brands. So many of its products are dupes for MAC and others. I am in love with NYX eye shadows, blush, lip glosses, liquid eyeliners and pencil liners (they don't smudge!). You'd never think they're only a few dollars! I've converted lots of my makeup snob friends. Also I'd avoid things such as HIP which test on animals. NYX doesn't :)
