I am notorious for losing earrings & have been afraid to wear my nice ones. I have a couple pairs with screw posts, but they irritate my ear holes, so until I found these, I thought I was SOL. These sat in my shopping cart for months before I finally took the plunge. $50 seems like a lot to spend on a set of earring backs, but I fell in love with a set of Montana sapphire studs that I do NOT want to lose. These Chrysmela backs hold my earrings securely in place and now I can wear my expensive (or cheap) pieces without having to make sure they're still there every 5 minutes! Another plus is that these keep the posts from stabbing my head if I happen to lay down while wearing them.

 I'll update my review if they randomly fail or break, but so far, I am very satisfied and am planning to get a set in a different color!
