I was hoping these would be easy to use and I was right! They work similarly to a bamboo necklace clasp, so they are really simple to open and close. Only cons are that they are nearly straight when open (you can drop what you have on it) and the cable spinning end moves freely (it likes to drift to the other side if you're not careful). Neither are huge problems; I think they are easier to use and more reliable than the big clasp rings.
