Nite Ize S-Biner MicroLock, Locking Key Holder, Stainless-Steel, Black & GS1-01-2R6 G-Series Dual Chamber Carabiner, Size #1 2-Pack, Black

I got these because they are small and I had been having a problem with the common metal rings used to attach keys to key rings catching and pulling my good clothes. These lock tight to prevent keys from working off the key chain. I love them because they are so small, secure, and don't ruin my good knits! Someone said they are impossible to unlock. They can be difficult the FIRST time, especially for someone with arthritis, weak hands or large hands. I used a needle nose pliers the first time. I don't yet know if the locking mechanism will be sturdy enough to hold up over a long time and much use but I think they are well made so they should last. I LOVE THEM.

Bought these for my keys to keep car/personal ones apart and it works beautifully! Love that is has a little lock so the carabiner can’t open when you’re not expecting it to (this has happened to me multiple times with others and I’ve almost lost my car keys).

These carabiners are amazing. The lock is a lifesaver so my AirPods case stays locked while I use the other side to attach to my bag which I can also lock separately.

I got these so I could connect smaller items to my backpack, but have now also been using them as a temporary lock / theft detergent while traveling. You can connect either side to your bag's zipper pulls which will connect your zippers shut while you're walking around in public. Gives me piece of mind to walk with my backpack or sling on my back.

Durable, lightweight, functional.

Got these for my dogs’ tags, they keep coming open & the tag keeps coming off.

Don’t know what to say about these other that they work and are good.

These are very handy little carabiner clips. I initially purchased a set of two Size #1 S-Biners as part of several different items I wanted to try out along with several other products in my search for the most suitable combination of rings and clips to organize my keys, and I've since added a selection of these S-Biners for various uses.What I've learned is that Nite Ize produces these S-Biners in various sizes and materials and finishes, each suitable for certain purposes. They're all well made, and in my opinion they are all a good value. I particularly like the locking models that are also available, both this small MicroLock size, and the larger SlideLock(see the models at the bottom of the listing below).This locking style S-Biner is particularly useful since it reduces the chance that something attached using this clip will become accidentally released, which is something I've had happen when using the non-locking style slip. This particular locking S-Biner is only available in the very small size, so for someone who wants the locking feature then the other locking style should also be considered since it's available in two larger sizes.After going through a mini research project of my own in order to both determine the relevant dimensions of the various sizes, as well as find the best listings for them on Amazon, here is a guide to simplify this process for others.IMPORTANT NOTES:- I've done my best to determine representative listings here on Amazon for each of these models. Please keep in mind that these are sold by a variety of sellers here, there are multiple listings for the various different sizes and finishes, and the listings are not always well described such that you can be sure that you'll receive the correct size listed.- The prices also vary widely and from my own observations of the various listings here on Amazon, the best prices are usually for the Amazon 'Add-on Item' listings. It is sometimes necessary to take care in going through the choices available on some of the product pages in order to find those listings and prices.The following listings links are the best I have determined on Amazon at the time of posting this review:--  S-Biner, Size #.5, SBHLF-2PK-01 : (available in stainless steel or black, 2-packs)Dimensions: 1.31" x 0.48" x 0.22" | 33.41mm x 12.40mm x 5.74mmWeight: 0.11oz | 3.00gWeight Rating: 3 lb.--  S-Biner, Size #1 : (available in stainless steel or black, single-packs or 2-packs, part number begins with SB1)Dimensions: 1.56" x 0.62" x 0.21" | 39.67mm x 15.86mm x 5.50mmWeight: 0.14oz | 4.00gWeight Rating: 5 lb.--  S-Biner Size #2 : (available in stainless steel or black, single-packs, part number begins with SB2)Dimensions: 1.95" x 0.85" x 0.24" | 49.75mm x 21.71mm x 6.15mmWeight: 0.25oz | 7.00gWeight Rating: 10 lb.--  S-Biner Size #3 : (available in stainless steel or black, single-packs, part number begins with SB3)Dimensions: 2.67" x 1.18" x 0.26" | 67.97mm x 30.09mm x 6.83mmWeight: 0.49oz | 14.00gWeight Rating: 25 lb.--  S-Biner, Size #4 : (available in stainless steel or black, single-packs, part number begins with SB4)Dimensions: 3.52" x 1.57" x 0.31" | 89.41mm x 39.92mm x 7.94mmWeight: 1.06oz | 30.00gWeight Rating: 75 lb.--  S-Biner, Size #5 : (available in stainless steel or black, single-packs, part number begins with SB5)Dimensions: 4.38" x 1.93" x 0.33" | 111.41mm x 49.19mm x 8.45mmWeight: 1.69oz | 48.00gWeight Rating: 100 lb.This  Nite Ize S-Biner 3-Pack  is also available and includes one each of sizes 2, 3 and 4, in either stainless steel or black. (Part number begins with SB234). This is a better value if you want to get these particular size S-Biner's.There are also a couple of variants to the S-Biner product that incorporate locking features to better secure the two gates and prevent them from accidentally being opened: Nite Ize S-Biner SlideLock (size #2 or size #4)  (Part number begins with LSB2 or LSB4 for size 2 or size 4) Nite Ize S-Biner MicroLock  (size is between the regular S-Biner size #.5 and #1) (Part number begins with LSBM)Nite Ize also offers the same style product but manufactured in plastic, in sizes 0, 2, 4, 6, 8 and 10, in various colors. For example, here is the  Nite Ize SBP4-03-01BG black #4 size plastic S-Biner . I can't include listings to more of the plastic models here because Amazon limits the number of links to 10 in any review. The size and weight ratings for the plastic models are comparable to the metal S-Biner's.Nite Ize has a very broad product line of hardware products, and it's helpful to go to their own website in order to get the best descriptions of their products as well as representative MSRP pricing, before making final purchasing decisions here on Amazon.

Resistente y de muy buena calidad

Bastante útil para todo tipo de engate rápido. Bom acabamento, resistência.

I love this company's S clips in general; I already had a few before buying this pack. However, when I opened this pack, all of the lock toggles on these were incredibly hard to turn! It physically hurt my fingers to turn them. I'm really hoping that they soften up a little bit with some use, because it's brutal.Hopefully it was just a bad batch.The anodized colour on them is very pretty though!

I like it. I use it on my keys and no problems so far. It's light weight but feels sturdy

Suficiente para la vida diaria sin necesidad de gran resistencia
