I own 3 of these eye shadow palettes: 501, 505 and 510. The shadows are well laid out in an eye-shaped diagram, with instructions on the back in case the layout is not clear. Each palette also comes with 2 double-ended eyeshadow brushes, which is great for applying the three different shadows, as well as the primer and sparkle shadow.
The colour combinations are well thought out, with a highlighter shadow up top, the darkest shadow for the crease, and an intermediate shade for the lid. However, with 510 I found the gold highlighter was too bright, and overpowered the other shadows. I also though it clashed with the other 2 colours. But the colours probably looked extra bright on me because I am very pale. The combination may suit other people better.
The staying power for the shadows was good. It is great that they come with a primer, and I think that really helps to keep the shadow in place. The shadow is also fairly easy to apply over the top of the primer. The only part of the palette I was not so impressed with was the glitter top coat. I found it was not really very noticeable over the top of the shadow. But the shadow looks great without it so I would not consider that a major drawback.
Has better colour payoff - finer mill so easier to blend and more colours. This one is good value for money
