The ring itself is fine in terms of function but if you have any sort of sensitivity to metals this will irritate your skin. I usually just buy jewelry from places such as hot topic and that grade of metal never gives me any problems but this made me develop a lot of the little crusties and also there was considerable swelling to where I had trouble putting in a normal post.
I used this for a conch piercing and the 12mm size worked fine, if I was to order again I would probably order a 10mm in order to make it a bit more snug. Overall, if you don't have sensitivities to certain metals its works great for the price but if you do I'd suggest ordering elsewhere.
