Love 'em!
I got a black one and a white one in the narrow/medium size.  I'm not sure if they are consistent with the sizing but my black on is a little smaller (like each string is just a little thinner) but it is fine.  I have 6 1/2 wrists and I can fit my hand into a Pringles can so I didn't have trouble getting them on.  They have shrunk up nicely and now they don't flop around but aren't tight either.  I do the yin/yang with black/white on one wrist. I hope the black will hold it's color for a while.
