I like them a lot! At first I almost returned them because I found them so painful to take in and out, and the chain hurt my ears. I found that generous amounts of anabiotic ointment saved the day.  I suppose any petroleum would do.  I  read a lot of reviews.  A few people complained about them tangling, or getting caught in their hair when the hair is pulled back. They do these things a little bit, but its not enough of a problem to get me to dislike the earrings by any means.
 They seem sturdy. Also I have worn them every day for a week, and there has been no change to the shine.  I am a happy customer
