I've used this eyeliner for six years, and I love it. When you first use it you have to run it over your lid a few times for the color to come out, but after the first time it's fine. I use ebony, and it's perfect, not too dark. It's also not a pencil, which is something I like. Also, I wear contacts and have never had a problem.
My only complaint is it doesn't last all day. Luckily, it doesn't smudge or anything (it even lasts through a few tears!) but it will fade throughout the day. I usually go over it with liquid liner (also by L'Oreal) and it looks much better.
This is my ultimate favorite drugstore eyeliner! It is very comparable to Smolder by MAC. it is so creamy and is so pigmented i use this for my water line and i dont have to apply this roughly. So smooth and so great!!! I just wish this came in white so i can use it for my waterline.. i:(
