This isn't a terrible product. The pencil part is creamy, and I like that it's a retractable pencil, so you don't need to sharpen it. However, the tip breaks easily when you use it. Also, since the tip is so small, it's hard to get the eyeliner to glide onto your lid without tugging. I've used this product for weeks, and I still haven't managed to get it to go on without tugging and smudging. The Rimmel Scandaleyes Kohl eyeliner goes on far more smoothly. However, the NYX eyeliner is more smudge-proof than the Scandaleyes, and the packaging of the NYX pencil is definitely better.
Overall, it's OK. The price is pretty low and the packaging is convenient, but I don't like it enough to repurchase.
