It is not an entirely trouble-free formula. First coat is patchy if trying to apply a thin coat, and runny if trying to add it a little richer. A bit difficult to clean up all polish around the cuticles. But the second layer is much easier to apply. It covers all bald spots and ends up on the nails and nowhere else. And I think the beauty forgives the formula a bit :-)
The color shifts from an almost turquoise, to dark blue, to purple, to deep red. The holo effect is a bit fickle, in some angles non-existing and in other quite strong. It's an exciting nail polish with all the colors and effects.
