I really like these lipsticks and there is an excellent shade range. I love love love the packaging. I currently own 5 shades, Androgyny, Rose Matter, Redrum and have recently bought Fully Nude and Birthday Suit. In the past, I have owned Celebrity Skin and Dreamhouse.
Each lipstick that I have tried works very well for me and all the shades I own are very consistent in quality. They are really pigmented and the shades are very bold. I don't need to use much when applying them and they apply smoothly and evenly on my lips. The applicator is very easy to use, and when paired with the lip liners are even easier (I own lip liners for the shades Redrum and Androgyny). They last very well compared to other liquid lipsticks I have tried and the colour stays bright and bold. I find they do come off a bit when eating.
I don't like using these when my lips are dry, they emphasize the dryness. I need to make sure my lips are hydrated before use, which I do when using any other liquid lipstick as well. These lipsticks don't dry out my lips, but they don't hydrate them either.
I think that there are cheaper alternatives, but I do really like these lipsticks. I will be buying more shades in the future.
