I really liked the color, the staying power was quite average (about 3-4 days without chips) but the brush was the worst- to me, it made the application horrible and had to do more clean-up than usual.
If you really love the color, I'd suggest you decant it into an empty bottle.
This is a terrific royal/electric blue shimmer. It's bright, but not as bright as Color Club Neon Jeweltone Blue and much better with my pale neutral complexion. 2 coats for full coverage.
Bleu Magnetique is a deep almost royal blue. Shimmery as all (my) Bourjois polishes are, long lasting and a single coat covers well.
