Review (1/5): Run, Don't Walk, Away!
I had to use pliers and brute force to remove the back in order to get it off my wife's ear. She had to hold her diamond earring steady with her fingernails or else I would have pulled the earring back through her ear. The situation was completely frustrating and ridiculous; she said she should have paid attention to the other reviews that warned this would happen. These things are IMPOSSIBLE TO REMOVE if your post has any grooves or ridges in it, as hers did.
