Nite Ize LSB3-01-R6 S-Biner SlideLock Dual Locking Carabiner, Size #3, Stainless

I've been using the Nite Ize SlideLock S-Biner for a few months now, and it's become an essential part of my everyday carry. The dual locking mechanism provides peace of mind, ensuring that my keys and other items stay securely attached. The stainless steel construction feels sturdy and durable, yet it's lightweight enough not to be cumbersome.​ The size #3 is perfect—not too big, not too small. I use it to clip my keys to my belt loop, and it holds up to daily use without any issues. The SlideLock feature is easy to operate, even with one hand, and it prevents accidental openings, which was a problem with my previous carabiner.​ Overall, this carabiner is a fantastic product that combines functionality with security. Whether you're using it for keys, gear, or other items, it won't disappoint. Highly recommended!​

This clip is awesome. Super sturdy and spring strength is strong. I love it has the security lock it it so it just won’t open which is genius. But you can easily unlock and remove with no hassle. And it’s the perfect size for my magnet water bottle bag.

this “S-Biner” carabiner from Nits-Ize is very good, very affordable and very sleek. It is locking which is very handy and very delightful. I highly recommend this because it’s so cheap. You really can’t go wrong with something that is this inexpensive and it is very cool because it quickly connects to your belt loop and when your belt loop has your keys on it. It is much easier to get your keys then if you have to rifle through your crowded cluttered pant pocket or purse for the ladies. This thing rocks. Also, it is locking and the locking functionality is very fun to play with.

Works pretty well if you don’t want somebody to be able to quietly open your carabiner. Basically each side has a little nubbin that slides into place to prevent it from opening. Took me a little while to get the hang of it. You basically lock both sides separately. It’s a litter expensive for what it is, but still. The other kinds that have screw on doohickeys cost more and are somewhat more difficult to open. I got this to keep my car keys in place on the strap of a sling bag. Works pretty good for that. Probably works best for emergency type stuff that just has to be there when you need it.

I've been using this for my keys for years now and it's held up extremely well. The locking mechanism still works like new. Appearance is definitely used after years of wear and consistent handling, but it's faring better than anticipated. The thickness of the S metal does make it difficult to get something like a car fob onto it and makes moving that object harder, but for most keys it's completely fine.

Great option to secure two items together. I gave it 5 stars as this brand has always been very secure and durable for me in the past. I like the design has a locking feather on both sides BUT (and that's a big but) I don't like it for my intended use which was to secure keys or car fobs to my belt loop. For that purpose this is very secure but since I take the keys off & on frequently the locking feature is moot and I really don't like it for that. I didn't send it back because I will find plenty of other uses for it that will take advantage of the secure locking feature. For keys NITE Ize has another style that has two locking gates inside one another. Hard to describe but search by brand and you can find it. It's amazing and what I use daily now. Actually about to purchase a couple more.

High quality carabiners that lock in place to prevent losing items. I rely on them heavily and highly recommend. Purchased several times.

Great addition to my travel gear. Good size, durable, easy to use. I bought the smaller one. My intention was to be able to use it to hold my backpack or purse in the restroom if there is no hook available in the stall. I can clip it on my item and put the other hook over the door to keep my items safe. It has good spring strength. I can also use it to clip my zippers together on my purse or backpack and have extra security when traveling.
