I absolutely plan to buy these again.  These have been perfect for my sensitive second lobe piercings.  They seem to react to every metal, but I have had no issues with these.  The backs are a bit long and very sharp, so I find it impossible to sleep in them. It is also very easy to lose the backs--some are loose, but mostly it's because they're so light in color that they are hard to find if dropped.

They are small, but not crazy small.  I find that they look nice without being distracting or overwhelming.
