Doesn't feel like I'm wearing it.  Very comfortable.
Nice!<br /><br />Update----<br />I've had it since April and still satisfied.  A bit of a challenge putting it back in once it's removed but aside from that I really like it.  Doesn't feel like I'm wearing an earring at all nor does it bother me when sleeping.  I really like the design and wish it was a tad thicker so it'd show more but then it'd be heavy I think.  Overall it's perfect for me.
