I've tried basically every clip out there, and these are by far my favorite!
Mine are rather rough at the edges - like "catch at your hair" rough. I suppose I could smooth them out with a rasp, but I haven't. They're much too heavy for my thinner hair. The spring is very strong, though and they are longer than the typical 2-prong clip/
Not my favorite. They are QUITE heavy. They really do not outshine the smaller metal clips from Sally's or other stores.
