Love the concept, but it's just not practical when people have such different eye shapes. You can trim them, but it's really hard to get both sides looking exactly even when cutting with scissors. When I put them on, it didn't look natural at all, but when I wore them with my Halloween costume, they worked with my look but didn't really save me time since I had to trim them to fit my eyes. They did stay on pretty well, though. It's a fun novelty item, but probably wouldn't work for a lot of people.
