I've had my custom ring for more than 4 years now. I started with one that says "Be Brave" and added another to the collection that says "Memento Mori."
The rings are very good quality and are just as nice as the day I got them. I've worn them during the day almost everyday since I've gotten them and wear them through normal hand washing (and now-a-days, hand sanitizing) and they've held up great. I don't work out with them or anything like that.
The rings are dainty and just small enough for the message to really only be read by someone who's really close to it, so since the words on it are more of a reminder for me, I really appreciate their size.
Also for sizing, they're very accurate with sizing, so make sure to order the right size for you.
Customer service is great too, there was a bit of a hiccup with my second ring and they were quick to help me and get a replacement to me quick.
