These are really nice and slim tweezers. I carry one on my keychain, and one in my emergency kit. The locking style seems pretty strong right now, and i don't have any issues with them coming loose in my pocket or falling off the clip. i actually started using these as soon as i got them, they helped get some small screws out of a screw-hole :p

shipping was pretty fast, and i had no problems with the order, very satisfied.
