I have had this for a short time and have used it maybe half a dozen times, but I really like it. I get a better result when I can place the still unfinished necklace on the form and find out that it isn't the length I thought, but shorter. It is hard to judge without constantly going in front of a mirror and holding the unfinished item up to yourself, whether the beads are taking up more room than you think. (ex. an 18" necklace won't hang correctly if there are larger beads used. The larger the bead, the smaller the inside circumference of the necklace as compared to the circumference of just the wire measurement.) All beads take up room. I highly recommend this tool.
