Mine has been fine since August so I am ok. They said they'd exchange it if any more issues. I have 4 love bracelets and this is the first one that ever came loose after taking it home.My came lose and fall off. I stacked my with another love and crash bracelet.
My SA sent it back to change the mechanism of it back in September. I wore my everyday since then and had no problems. I haven’t tighten it since.
You should ask your SA about this service. It’s free as well.
Glad yours got resolved, these are expensive creations!
