It wouldn't stay on.
This is a pretty little cuff, but it's much smaller than I thought. FYI, It does not fit around the middle part of the ear.  I could not get it to pinch onto the top part of my ear after working patiently with it for quite a while.  I really wanted it to work. it just wasn't going to stay on, and was difficult for me to open and close. I was worried about breaking it, since the note that came with it specifically warns against bending too much. Frankly, I couldn't really get it to bend much at all, or maybe it would have closed enough onto my ear to not fall off when I moved my head.
