I looked at these es in person yesterday. I really liked most of them, and they seemed to have decent color payoff - with the exception of Andromeda and Cassiopeia. The texture was what I was expecting which was a buttery powder and not stiff at all. A bunch of the colors are dupable, so check your stash before purchasing.
I ended up purchasing: Subra, Europa, Callisto, and Himalia. I used all four in a look today and really like the results. No fading so far. Europa applies a lot nicer over primer on the lids than it appears in a swatch on the arm or hand. I haven't tried them wet yet.
I am happy with my purchase, but I do not know if I will be getting more of these b/c of the price.
ETA: I tried Europa wet today and really liked it. Though I agree that it is dupable, it is a really nice base/lid/highlight color. I also went back for Phoebe and Desdemona
. Now I think that I am really done.
