Bought these with the hope of making handling beads easier. Instead I added the difficulty of finding the bead after it shoots out of the tweezers. If I find it, I can then use my fingers as before. There is a dent that is probably hoped to hold the bead firmly, but it's way back in the tweezers. It would be hard to get the bead back there and then, the best I could hope for is to drop it in a better location.
Maybe mine is worse than these other reviewers'.
