I liked the small size of these - perfect for the 2nd hole in my ear.  The colors are bright and many choices.  They are very comfortable.  The only things I was surprised about was that it's not actually 18 DIFFERENT colors, only 6 as there are 3 sets of each color - but this has worked out in that I lost one and have a replacement!  Also, the backs are plastic - which is good if you're allergic to metal - but they tend to bend when trying to put the backs on.  Excellent for the price though.
