The ring is ansich very nice and looks damn good, only if one loosens the screws you feel it already ..... The edges are sharp and damn the region where supported, this is not pleasant. I did not know now what hurt more, the sharp edges of the searched your path or extend the existing hole from piercing ...... After 5 hours, it was then, I myself exhausted and pain without end ... .. With less sharp edges it would have been more comfortable ......
