It is literally light as a feather.  This is my 2nd ring and I'm thinking it's going to be the main one I wear.  Very slim.  Very comfortable.  I can play guitar with it on without it banging on the neck.  And it looks good.

Update: Lowered it to 4 stars.  Unfortunately, it's not as durable as you'd think titanium should be.  After a few months I have a few scratches and seems to be hard to clean to make it shine really nice.  Still, I like it enough.
