Just got these but heres my thought right off the bat. I read a ton of reviews before buying. For the price I decided to go with these. Comment1: like other reviewers I found these could screw on tighter. The posts are a bit long compared to the others I have. But? They aren't falling forward like others claim. Itll depend on your ear shape and thickness. All of you will be different! So suggestion for the makers: improve the post. Allow a few more twists so they fit more snug on the ear. Comment2: they are sparkly Iike others say. Do they look like real diamonds? Not sure but they sparkle so theyll do. Comment 3: delivery was fast. Comment4: came in a nice box like others said. Its presentable lets say. If you gave these as a gift. The box isn't a cheap cardboard thing. Looks decent. Comment 5: careful putting the backs on! I dropped the backing twice and I almost lost it. Had to go on hands and knees to search for it. I have short nails and it just felt small to hold between fingers. So? Advice! Stay away from the bathroom sink when you put them on in case it falls in! And make sure your hands are dry and grips well. The backs are hard to get on. Aint gonna lie! Once on though? Its like an easy bake oven. Set it and forget it. They seem to stay in place. Comment6: I bought the 4mm. I have a 3rd hold where I wear a 3mm. The 4mm were perfect for my 2nd hole. These I got for my 2nd hole. So Id say they r good size for 2nd hole for sure. I wouldnt go 5mm on second or third hole. But I like the pattern where it gets smaller as you go up the ear... overall 4 stars. Id have given it 5 stars if the backs were easier to get on and the post would allow us to twist the back on further. Just bought these so first impressions. I can update later on to let you know if they still look/feel good. I plan to wear these daily and sleep in them. Btw the backs of these r comfy. I don't think  Ill get poked as I sleep. So thats also a plus. I don't like the butterfly backs on other earrings. They do Poke. Screw backs all the way for comfort and secure fit. Plus you can rest assured they won't fall out. Just make sure the back is screwed on well. They won't go nowhere! Overall I like these. Id buy again if the posts were shorter or allowed tighter fit. Makers! There are enough comments from many customers here about the posts being too long. Get with your production team and make that better will you! Allow more twists for better fit. I cant inagone a baby wearing these. Their little ears would definitely have them too loose! Im an adult. And on my adult ears they r too long. Dont buy these for your baby or toddler. They will for sure be too long.
