This is a great, although expensive, mascara. I prefer this over Definicils, which seems to be included in every gift with purchase. It goes on evenly and neatly, unlike Definicils which creates nothing but a sloppy clumpy mess. The brush is uniquely shaped, almost like a 3D triangle. It lengthens and separates my lashes. What I like best is that I can reapply it over my existing 2 coats 4-5 hours later and it goes on as smoothly as the first coat.
