I love the ergonomic shape of this product. It's so easy to hold while using it. I also love the non-glossy effect. However it doesn't really stay that long especially if you have oily eyelids. So you have to reapply. That's the only downfall of this eyeliner. Other than that, this product isn't that bad. I'd buy it again.

I paid $10 for this eyeliner and I really wouldn't waste my time and money on it again. The first two applications were ok but not super impressed. By the third time it had begun to dry out despite being closed correctly and I had a really hard time getting it to be pigmented. I would have to go over it three or four times to get the really black pay off. It also broke apart so that made applications even worse. I really tried loving this eyeliner but unfortunately I never could. Bye Bye

Usually, I'm a gel liner kind of girl but unfortunately, gel liners can be fiddly + tricky on the best of days.. especially if I'm in a rush! That's where NYX's curve liner comes in. After you get used to using it (make sure you hold the grooves on the end, it's easier to hold it this way), it can produce a nicely pigmented, easy method to line your eyes. Now it's not the HG of eyeliners by any means, it is a felt liner and will not produce the same striking effect that say a gel eyeliner would provide but it is an excellent little product if you are short on time and but still needing a decent winged liner. update (30/05/15): I removed a star because I've been noticing how much this stuff fades throughout the day, it becomes very dried out very fast. Will not be repurchasing.

By far the best liquid liner I've ever used. Long lasting, easy to apply (weird at first but you get used to it). I am not very good with creating winged liner but this liner did the job. I would recommend this to others who struggle to create that perfect winged liner. Will definitely be buying again!

LOVE LOVE LOVE this product. I am an eyeliner addict and have tried so many different types from pencils to waxy pencils to liquid liners to liner pens and everything in between. The ease of use of the NYX curved liner is great, though a bit weird at first but I quickly got used to that. I can create cat flicks very easily and it surprisingly does stay put all day (I have extremely oily lids so have a lot of trouble with eye make up disappearing or sliding off). The only gripe I have is that it isn't waterproof. It says water resistant but when you have very watery eyes like I do you just need to be aware of this. Overall I would definitely be buying this again!
