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

I use this for my daily keys to go everywhere. Simply hook it onto my belt loops and I havent had any issues since. The locking feature is great so I can lock the entry so the keys can never pop out accidentally. Great purchase and I bought a few more too.

Perfect size! Hubby loved it.

I needed a key ring that lets me take some keys off the key chain quickly and easily and put them back on the same, but was also secure and not worry about keys falling off. The locking mechanism works extremely well. I cant see how a key would accidentally fall off if the lock mechanism is closed, and you can quickly and easily open it when needed. The only reason I say sort of in my subject line is that I originally ordered the size #2 which was a l too small, and the #4 is way too big. I wish they made this locking version in the middle. A number 3! :-)

Very versatile biner. Functional and strong, not too much else to say. Quality craftsmanship.

Plastic lock is not really handy if you want do it quickly unlock. Generally is good quality but I would not buy it again. I would buy leatherman clip for about the same price on their website. Not bad and not perfect as well.

Work

I use it as a keychain. It works perfectly, the sliding mechanism is very easy to lock into place and also vice versa. Feels very durable and I love the dark black finish on the metal. Will definitely be purchasing more in the future. For the price of $5, with prime. Its a great deal.

This key carabiner is stylish as well as utilitarian, no longer am I worried my keys will fall off!

Perfect solution to the s beaner. Ive lost keys while using the regular s beaner. This one locks and hasnt caused me to lose anything. Just lock it and it stays put.

Great
