I love these. I use them to hang my patio lights onto my patio umbrellas & my camping trailer's awnings. They work awesome. I bought the small clip but not enough to grab onto once the cord is there. Small ones do work but I wouldn't trust them on windy days as I would with the medium size.
These binder clips are the perfect size to "bundle" a group of important papers. I am pleased with the strength of the clips and have very useful they are for all my projects.
