Update: It's November 2015, These things are still amazing, they still look great! No issues with the quality, the posts are still in, nothing looks bad, etc. Still as good as new. I recommend products from the Amazon Collection, they may be inexpensive but they are not "cheap".

Update: It's December, and I still rock these just about everyday. I LOVE these and you can't complain about the price, the quality is higher than what you pay for. I'm impressed.

UPDATE:
I bought another pair of them after loosing one of the earrings to the jewelry troll who likes to take one of my earrings in any particular set. The new pair is just as nice and I am completely happy.

I bought these in May and It's June now, I've worn them almost everyday not taking them out for showers, leaving them in at night, etc. No problems, they still look great and they are good quality. I have VERY VERY sensitive ears and I thought for sure these would bother me but I figured at $5, it's worth a shot. I had a very expensive pair of pearl earrings with 14k gold and I lost one, so I was desperate to replace them. Even the 14k gold earrings irritated my ears from time to time.

Sure, they are not super shiny like the very expensive akoya ones, but these are still very nice. I know it says button, but at this mm, you don't see them as button, they look a little rounder and does not have that smushed button look to them.

I highly recommend these. Also, they have a bit longer post to them, which for me is nice because if the backing ever does fall out, the post is a little longer to keep it in.

I hope these stay on sale for longer because I am recommending them to my friends and they would make great Christmas Presents.
