I haven't used the product yet but it is simple mathmatics so I am sure it will work well. It did take longer than usual though for Overstock to ship it. After checking the tracking it looks like it was sent to the wrong shipping depot then came back to where it originally left and was resent to the correct route. I do know that I waited a lot longer for Overstock than many others I order from including Amazon.com

Easy to make jump rings all the same size. It is less expensive to make my own jump rings therefore I am very happy with this jig!
