After reading other reviews, I kind of knew what to expect with these inexpensive earrings.  I just received them, so I don't know yet how they'll hold up, but I wanted to write a review to note a couple of things.  The 6mm earrings must have a little larger post or something, because the backs are so tight it hurts my fingers to pry them off.  I couldn't even do it bare-fingered, I had to use my shirt to protect my fingers to get the backs off.  I need to find bigger backs before I actually put them in my ears, or maybe I'll see about exchanging that pair.  The other sizes seem to have backs that fit okay.  One pair of earrings came with a bent post, but it's still wearable.  Otherwise, the earrings appear to be just like the picture.  I'm happy with my purchase, but that's because I knew what to expect before ordering (bent posts and weird backs).  You get a nice range of sizes of silver ball earrings for a reasonable price - not top quality, but fair for the price.
