Same here. I got Palladium, since I figured if these crease and fade I'll be better off with one of the lighter shades. I have to say that it doesn't crease on me though, BUT it fades so quickly. As soon as I try to spread and blend it, the colour fades and there's just a sheer layer of a silver shimmery sheen on the lid. Which is nice if this is what you are looking for. But honestly I expected a more opaque finish. I tried it on bare lids and with Painterly as a base. I also tried to put different powder e/s on top, like the Mega Metal ones and regular ones like Vex, but it doesn't make much of a difference. Another downside:
I have a hard time picking up the product with a brush. The e/s texture seems too hard and just doesn't really stick to the brush, if that description makes sense. Eventually I got so annoyed that I used my finger to apply it, which worked quite well. But probably wouldn't so much with the darker shades, I can imagine. I don't think this is a bad product after all, I actually would say I kinda like the texture, like I said it doesn't crease on me. But the fact that the colour fades this quickly and that all it does is leave this light shimmer, is disappointing. You could still use the lighter shades as a nice highlighter, even on the cheeks, IMO. But if you're looking for an e/s that you can put on and wear all day, I don't think these are a good choice.
