I love these because you can clamp them onto just about anything and you're good to go! My son LOVES to stare at and play with them! One of the really great features is the rippled clamp--because of the wavy/zig-zag texture of the inside of the clamp, you can clip it onto a lot of different shaped objects and it won't slide or twist around. The elastic/scrunchie tether, crinkle wings, and jingle bell really keep my baby's attention.
