If I could, I'd give this shadow a 4 and a half. My issues with it are really minor and nothing to do with the product itself. What I dislike is the price, and the packaging (cardboard?? I knew about it beforehand, but it really does fail to impress me). If you're going to spend money on this line, spend a bit more and get a palette (the e/s pans are $21 CDN each).
The color itself is gorgeous. It looks like a medium smoky purple in the pan, but on the eye there are pink and silver tones---it's really beautiful. Application is really smooth, the shadow is easy to blend, and it lasts a fairly long time without creasing. It seems bit more 'crumbly' than most of my MAC shadows, but that won't stop me from buying more of these. I don't know if I'd bother with neutral shades from this line (you can find approximate colors for less) but for a unique and pretty shade like this, it's worth it!
