These connectors work well with the 1.5mm diamond cut ball chain, but they are a doozy to attach to the chain! I had to try at least 25 times before I was able to get it to work. Once you get it to connect, it's beautiful, but they are really small and kept falling out of my hands as I was trying to make the connection. Delicate and pretty, but very frustrating!

I found these connectors impossible to work with. I returned them. Maybe someone with small hands/fingers would be able to use them. Too bad because I love the tiny ball chain.
