My husband bought these for me for Christmas.  They are a good size (I am a big person and small studs get lost on me), very attractive and are very comfortable to wear.  The only problem I had with them was the butterfly backs, which are very small and are difficult to put on, especially with long nails.  One post would not go into the back at all until I discovered the butterfly was too tight, easily remedied with a screwdriver to force the loops apart.  I am very pleased!
