I had these earrings for about 2 years and they were my everyday earrings for all that time. They are extremely comfortable and I can sleep wearing them without feeling uncomfortable. I have lost one of this earrings recently and I'm gonna buy a new pair. These are my favorite earrings.

I should update my review - May 2012.
I have lost one of this earrings, and decided to purchase exactly the same one. As a result I got much smaller earrings though I was purchasing from the same link and the same item... very strange. it seems they deliver whatever they have at the moment.
