I love knitty accessories, and this appealed to me. I got it today... no. The beads and the construction look cheap. And, although I understand the fine line between having enough friction between the beads and the ribbon to hold them still and not having *so* much friction that they can't be easily shifted... well, they just don't move easily. So, since the beads don't slide easily, and it's on your wrist picture chasing the beads around your wrist with your other hand's finger. Not smooth operation.
Finally, there isn't anything to mark the rows as a tens row or a singles row. Not color, not a mark, nothing but the convention of remembering which side is which. So, if it gets flipped around on your wrist, or turned over?
