I am a big fan of all ChiaoGoo Red Lace Needles, be they fixed circulars or interchangeable sets. I always have several projects at once on the needles, so I have multiples of my most common tip sizes. These adapters offer some nice versatility when I'm scrambling around trying to find this or that cable length, only to discover that it's already in use as a stitch holder keeping the sleeves of (yet another) UFO in place until I get back to them. (I really am going to finish that sweater for my son one of these days. Really.) I would highly recommend any ChiaoGoo red lace product without reservation. Now I just need a needle case to keep my fixed circulars tidy and I'll be all set.
