I love the color of this Swivel Cord. The installation is quick, and this interchangeable cord does not unbolt. The cord is very flexible; you do not need to immerse it in boiling water, which is great as it saves you the trouble. The only thing I noticed is that it takes an indentation right after the connector after only 4 days of knitting. That said, many other cords do the same thing. It doesn't affect my knitting.
It's also less expensive than Chiaogoo's equivalent and comes with caps.
I really like working with them.
