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

This is a great carabiner. It feels sturdy, the little locking pieces are handy and don't feel like they're going to wear down quickly, it's a reasonable size and thickness, and it's not difficult to lock and unlock when you need to. This brand also has a lot of good reviews from people in "Buy It For Life" communities for their long-lasting carabiners, and it certainly feels as though they're correct, because this feels really sturdy and well-made compared to other carabiners I've used before.

Been using it to clip my car keys and work keys to my pants for almost two years now. It's pretty solid metal and has a pretty good build quality. The locking mechanism is a nice bonus and is easy to work. Some of the paint has worn off which is to be expected after 2 years of heavy use but that's not a super big concern for me. Works great for clipping keys to your belt loops. 10/10

I love these S hooks, so much better than a D-Ring. They come in so many different sizes & colors. They are so convientent for everybody. You can use them for any kind of accessory, the attach so easily, and stat attached. You can also get them with a locking mechanism. I have a few of them but didn't find it necessary for what I use them for. I use them on my backpack for my keys, with my water bottle, it has a loop holder. The way you use these is endless. Very durable. Throughing my backpack around, I have never had one break or even scratch. Highly recommend

Good product! Like the new locking feature.

The first time I bought one of these was in the late 2010's back at a big 5 sporting goods. That particular clip is still working and being used for my house keys. Ever since then any time I need a new carabiner I always go for the nite ize brand and especially this particular locking s-biner. It comes in a variety of sizes but the #4 size here I feel is a good size for the hand with lots of room for clipping. The lock is easy to use and open, hard to accidently unlock. It gives me piece of mind that my keys are staying in place clipped to a belt loop. I've found plenty of other uses for this particular clip though as I use them in varying sizes for even keychains on my bags and plush keychains. Any time a clip or carabiner is needed for something I always recommend this brand to my friends and family. I've bought plenty of these and I probably will buy more in the future too. Definitely a good value for your money considering I have clips that have been going strong for years.

I got this s-shaped locking carabiner to be able to hang my little Bose speaker. I don't really need the locking capabilities at home, but I can see how it would come in handy for securing things while camping or while traveling. To unlock and open, simply slide the little piece to the end of the little lever. To lock, just slide on back down. Both levers have the locking mechanism, so this is a simple way to add a measure of security to your luggage, backpack, or purse. This size is about 3.5" long, so not so big that it gets in the way, but large enough to secure a nice size item. I have locked and unlocked this carabiner over and over, and it has stood up to plenty of punishment. In my opinion, anything this small and simple that really does what it claims is an excellent value. I'll be getting more of these in the other sizes.

I recently purchased the Nite Ize LSB4-11-R3 S-Biner Slide Lock Carabiner, Black, #4, and I have been blown away by its versatility and durability. This is a high-quality product that has quickly become one of my go-to tools for all sorts of tasks. The slide lock feature is incredibly convenient, allowing me to quickly and easily secure items to the carabiner without worrying about them coming loose. The carabiner itself is also very well made, with a sturdy construction that can withstand a lot of wear and tear. I have used this carabiner for a variety of tasks, from securing my keys to my belt loop to hanging a heavy backpack from a tree branch while camping. In every situation, it has performed flawlessly and exceeded my expectations. Overall, I would highly recommend the Nite Ize LSB4-11-R3 S-Biner Slide Lock Carabiner, Black, #4 to anyone looking for a reliable, versatile, and durable carabiner. It's a fantastic product that I'm sure I will continue to use for many years to come. Five stars!
