LOVE those earrings. I have a pair of click-ins almost exactly like those as far as the way the stones are set but mine were bought on Aruba some years ago and do not have the push release like these do. Mine you just pull it back out. Once I get them clicked in, and I don't find it all that hard as long as I'm close up to a mirror, I often leave them in for a week or two. I'm not one who takes their earrings out to go to bed.
If I didn't already have a pair almost identical to these I'd be ordering them.
