The ring is very cheap, almost free, the only thing is the shipping costs. That one of them not to expect too much, should be clear. Nevertheless, the ring is a small eye-catcher and can be bent into shape if necessary.
Staining on the ring can be easily prevented by smeared him with some clear nail polish! So I do not see this as a negative argument, which is in almost all nickel-plated rings in this price range that. For the price so deserved 5 stars.
