This is not my favourite eyeliner. I find that it skips quite a bit when you are putting it on - causing little skid marks instead of a smooth line.
The built-in smudger is handy though, and I like that you just have to twist to sharpen.

Stayed on for a while. Never smudged that much which you need for a cat eye!

it's a love hate thing i have. i wouldn't buy it again, but it was definitely a smooth application. but i found that it smudged too easily. it's great for the smokey eye look b/c it's really easy to blend, but i wouldn't buy it just for that one look.

I bought this eyeliner a couple months ago and am still using it. I kind of regret buying it though.

I find that the best things about it would have to be the smudger and sharpener on the other end and the fact that it glides on quite smoothly. But it isn't worth it! This eyeliner smudges wayyyy too much. I end up looking like a panda by the end of the day. I find myself wiping away the smudges under my lower lash line causing pre-mature wrinkling. If you want the smokey look, I guess this eyeliner would be for you. But if you want definition and a clean look, I would suggest going for a waterproof liner. And one more thing, this liner does NOT last long so I have to constantly reapply throughout my day!
