Nite Ize - LSB4-01-R3 LSB4-11-R3 S-Biner Slide Lock Carabiner, Black, #4

Shows no sign of breaking yet.

The locks work great.

Does not work to hold keys. My keys rub against the slider causing it to unlock. Multiple times my keys fell off because of this. It could work if they could create some kind of real lock.

Good to hang assceries to backpack or hang stuff

Fairly high quality. I play with my keys excessively and the finish is starting to wear off. It still looks good however.

Love the locking, working out great.

Great item lots of uses

Great to use for keeping your keys ON the carabiner! Locks in place and keeps keys from sliding off of the jaws from opening accidentally. I bought 4 for our key sets at work.

Nifty little thing. I don’t think I’ve ever used the word nifty before. I hooked one side to a fannypack and the other to a water bottle. Not fashionable but very helpful

I would never recommend this for a key chain. Had it several months and just started losing keys , key fobs , any on the loops. Not good.
