I've never broken mine, and I'm a pretty big klutz. How long have you been tying that you're just now considering one? It only took me two weeks to realize my thread would keep breaking until I bought a ceramic bobbin.

$8 seemed pretty expensive to me at the time, but it has been worth every penny looking back on it. I now use my old all metal bobbin for tinsel and wire.
