I had an "experience." Purchased a bracelet (less than 300, had to use up OBC), and it broke first time I wore it. It came with a lifetime warranty. Sent it off to the address listed, and it came back "no such address." LOL
Fortunately, I did have another Celebrity cruise booked, so I took my bracelet and envelope with me. That same vendor was on board (and it was a vendor not a store). So the bracelet was replaced.
BTW it broke again, very soon after I got home. 🤔
