Strong hands required
I would only use these to permanently mount something. It took all my strength to get the clips open and hooked on the bars of the cage, and I'm a strong-handed person. My partner who has rheumatoid arthritis would never be able to open these. Even I am afraid of pinching my fingers in them. That said, they are sturdy, the swivels work fine, and if you aren't going to move them often they should work great. I'll go with the chin-friendly clips in future.
