i received it a gift It looks great.  i don't need any of the claimed healing properties, so can't testify that but as a piece of modern accessory it is very sharp looking.
It is very easy to take out the pins, for size adjustment.  The carbon fiber inlays are very understated blue: Visible just enough.
As of day 1, I can't say a bad thing about - will post an update after vacationing with it on the beach
