I stack my PG Love bracelet with my PG JUC. I got the Love 7 years ago and the JUC 1 year ago. I don’t think the Love has scratched much but I have had a few issues with one of the screws coming undone, which never happened before I added the JUC. It was so secure before I started wearing the JUC. But I love stacking. I say just wear it and enjoy it
