I am happy so far. The size is nice (4mm 1/2 carat). The CZ sparkles nicely. I needed the white gold posts for my sensitive ears. It's not too big so it looks real and it's not too small so it still stands out. I was looking for something I could wear ever day and that looked like a real diamond. I've had these for a few days and so far they have been very comfortable. The backing is a bit different but so far it's been fine. They have not come loose and are comfortable. We'll see how they hold up over time. The one thing that was tough buying online in general was I couldn't find a picture anywhere of what the size looked like actually on someones ear. So I have added a photo. You really can't go wrong with these for $28!
