This is by far the best pencil liner that I've ever tried. Most of the pencil eyeliners I've used aren't black enough. This one is definitely dark. It glides on effortlessly, and stays put all day long. It is a bit difficult to remove, but most waterproof products are. I keep this one in my purse because it is so easy to use on the go. Highly recommend!
I have used almost every black liner on the market and this one is by far my favorite. It glides on easily and has a quick but workable dry down time. It really doesn't smudge or move once in place, but it comes off easily with makeup remover. The jojoba oil helps it not dry out too fast, and the built in sharpener is a nice touch, especially because this lives in my purse. I prefer this over Urban Decay's 24/7 and MUFE's Aqua Liner.
