Strong clips with a small profile.
I have fairly thick, curly hair.  It usually takes a huge clip to get teeth long enough and a spring strong enough to hold my hair.  I end up whacking it on everything (especially the headrest in the car).  These clips have a very small profile (the part you squeeze is small relative to the size and strength of the teeth).  They hold my hair all day long.  It doesn't matter if I clip back just a small portion of hair or all of it.  They hold up very well, too.  I had my first set for a long time.  Unfortunately I lost them one by one and now have to replace them.  But this is the first time I have had clips that didn't eventually break.
