I love the design and I want to love everything about it, but the silver metal piece that allows me to tighten or loosen the bracelet seems too tight. I wore it just a couple times and it's very hard to adjust. I think the bracelet is starting to fray and will break. I feel like I will have to leave it on. Most of my other adjustable bracelets have a different piece than the one on these that just works better. I hope to see an improvement in the future so I can buy more because they're a cool idea!
