I've also received 6 of the mineralized eyeshadows from the upcoming Electro Flash collection. And I have to say, they look better then I imagined.
I'm not a great mineralize e/s lover, because usually the color payoff is minimal, great for a light wash of color with glitters but not very pigmented. But in the case, it's very different, the pigmentation of the e/s is very good,especially the "mono" part of the duo e/s. The "melange" half of the e/s is more sheer, but that works great together!
I will try to do some comparisions with other e/s soon, so keep posted for more!!
