Review on Hamburger Shaped Earring Safety Backs - 100 Pieces of Secure Locking Silicone Earring Backs for Jewelry Accessories, 2 Sizes by Denise Davis

Don't give your money away! It's terrible! Pros: They are convenient and cheap. Cons - so many cons! Stud holes for earrings of all sizes are very inconsistent, they're bulky and worst of all, they won't hold, AND you'll lose your previous diamond earrings like I did! I am so angry! The back of the earrings is designed to hold the earring in place, but here it's the other way around! I have no idea when they fell off yesterday, just know they were securely in place when I put them on, a few hours later my earrings just disappeared, they fell out! DO NOT BUY THESE REPLACEMENT EARRINGS! You can't trust them with earrings!
