I tried it out at a store and kind of liked it as a lip stain with some shimmery pink gloss over it. The cool undertones with the pink made for a very nice lip color.
Anyway, if you come across it at a store, it is definitely fun to play with. If you want a nice standard rose shade, go with the Benetint! The Nars product also comes in a couple of other shades, but those seem to often be sold out online.
