Really nice, simple ring. I wear mine in my daith, but would work really well in a septum piercing too. Mildly fiddly to get in, but once in place I can't feel it at all. I love being able to have a different colour. (I got the teal one)
Advantages: Comfortable, secure
Disadvantages: Little bit fiddly to click shut once in, but not really a disadvantage since once it's shut it's not going to pop open easily.
