I love knitting with ebony so much that I will even knit black yarns on them. And lantern moon circulars are simply incomparable. The rotating cords mean you don't get them looped up while you are working. I was concerned because other circular sets I have had where the needles screw on to the cords....as you work the needles tend to "unscrew" themselves and you can find yourself in a mess, especially knitting lacy patterns. When I finally received my set after a looong wait they included a little tool that you are supposed to use after attaching the needle to tighten the connection and prevent this. So I tried it....but found that my needle could still come detached. They didn't give even as much info as I say here....and I truly wished it worked. But I still love the needles.
