I purchased this liner in brown instead of black to compliment warmer makeup. It's very pigmented and you do not need a lot of product for a strong line. The brush that comes with the product works fairly well with the gel liner as long as you keep it clean :~) Using this liner doesn't require a lot of expertise, and it doesn't dry down immediately either, so it's easier to clean up any mistakes. It is prone to fading and smudging throughout the day if you don't set it with a powder or eyeshadow, but the ease of use and pigmentation are definitely reasons why it is one of my favorite gel liners.
