I persevered with this one but I just couldn't get excited about it.
I found it difficult to apply, potentially due to the brush supplied, and once on it seemed to smudge very easily. Perhaps I would have a better experience with a different brush, but it just seemed a little too hard for me to get used to.
As a disclaimer though, I have been wearing liquid non-stop for years and this has been my first and only experience with a gel formula.
This is a good gel eyeliner. The texture is creamy, so it glides on easily. I've used the charcoal colour for a less dramatic look (as I am quite pale), and it looks really good. The brush works quite well. The fact that it is flat means you can turn it on its side for a skinny line, or have it flat for a thick line. It's brilliant that the brush is included - great for people that don't own an eyeliner brush.
Tips: Practice makes perfect! Even though this is a great an affordable product, you still can't expect to be amazing at applying it. Work on keeping a steady hand, and play around with eyeliner styles that suit your eye shape.
