I've been using the same Mac eyelash curler for close to ten years now and thought I'd give this one a try to see if it's any better than what I was already using. I really didn't care for this eyelash curler at all. It felt cheap and squeaked when I pumped it and pinched the skin by the outer corner of the eye. I compared this curler to Mac's and they definitely have different shapes. Mac's is a slightly flatter half circle (if that makes any sense), so this NYX one comes to a greater point at the center, which I think explains why it pinched my skin. Overall, I would definitely not buy again. I'm going to stick with my Mac curler.
