Great solution that only comes apart when needed, not unexpectedly. Solid and dependable locking mechanism that can be unlocked with a simple 1/4 turn. Small enough to be unobtrusive yet strong and solid.

Bought several of the small size of these to secure zippers on suitcases, backpacks and purses while traveling through Italy and they worked great! Hubby was fine with the black but I liked the fun colors. They hook 2 zippers together and then lock to further protect. Worked great! I’ll definitely use for further travel. Even used on our checked bag and held secure and super durable.

Excelente clipe multiuso para as mais variadas funções, a imaginação é que determina o uso. A construção é robusta e o sistema de trava funciona muito bem. Uso para prender meu canivete na bermuda/calça. Quem for adquirir deve levar em consideração que o clipe é pequeno mas não o torna inútil, mas sim bem discreto.

Got these after getting the stainless steel black ones to unnecessaryily colour match my keychains hehe, they are just as good but I was kinda surprised to see that they are thicker! Basically the same size and everything, other than that, might be a consideration for some as it can limit what you can attach to it, some things I've put into it have got caught up in it after being carried around for a while but I just now know not to carry it on these hehe. If you want as compact as possible then the steel ones will probably be best, most small split rings go on just fine it's just that some multi tools with built in holes have been just a little too small to work, but if it's not too much of a worry these are just as good! And a little more colourful :))

Il sont assez petit mais sont solide et sécurisé pour ne pas perdre ses clés ou autres

Los compré como cierre de seguridad para mochilas con cremallera.No resulta fácil de abrir, así que sin duda, un elemento disuasorio para carteristas.

These little S-Biner's are very handy little Tools. Top notch Carabiner Clips to be sure. I initially purchased a set of two Nite Ize S-Biner's as well as several other different items. This product and the other products were ordered in an attempt to find a combination of rings and clips to organise my keys, and I've since discovered that these stood out amongst the crowd and were so useful I couldn't not recommend them to anyone looking to reorganise their key-chain. They have various uses, various sizes and materials and finishes. They are all well made, and in my humble opinion these are a great buy and good value for the price. I particularly like these because they have this unique locking system. Which is very sturdy and does not break easily. There's also a version's that come without this locking system. I have not bought the other version's but they seem good too. I bought the black version. It's very simple and sleek, it really blends right in with some of the other gear I have acquired. You will hardly notice it which I believe is a good thing. I live on an Island and work on the beaches as a waiter so these would have been exposed to sand, salt and water and they still look brand new. I have heard the locking system can break and leave things coming off the Biner. This has not happened to me yet but it's something to consider. I hope this helps you make a decision.

Ottimo moschettone di piccole dimensioni,ma molto robusto!Li uso come portachiavi avendo piu mazzi da attaccare e staccare con facilita!Cio' non toglie che possa essere usato in mille modi diversi,vista la praticita' dei due ganci separati e la forma ad "S".Pratico anche il blocco che impedisce l'apertura accidentale.

I ordered the to use on my dog's collars and harnesses to attach their tags and lights to. And I have to say they work pretty dang well. I kept having to replace the key-chain style rings every couple of months because my dogs are big rough-housers and between the gnawing and wresting the rings would eventually get snagged and stretched out. We've lost a few name tags along the way! I finally decided to try something different. I bought 2 sets of these. I use one that I attached to the loop on the back of their harness which has a backup name tag in case their collar comes off for some reason, and I have the other one attached to their neck collar which holds their rabies/license tags. Although these locks are small they fit perfectly onto the large D-ring of their collars [so much easier than getting those keychain ones open]. The black is very simple and sleek, blends right in with their gear so you hardly see it at all. We live on the beach so these have been exposed to lots of sand and salt-water, not to mention the sharp end of dog's teeth, and they still look brand new. The only thing that kept me from giving it a full 5-stars is that twice I have noticed that the little latch had come out of place leaving the carabiner essentially open for things to fall off of. I won't rag on that issue too much, since I'm sure they weren't designed with the intent to be chewed on by playmates, but it is still something. Don't get me wrong, I would definitely buy these again in the future when we need them and honestly might just buy some silver ones to use on my actual car keyring. Definitely a great product!

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:-- : (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.-- : (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.-- : (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.-- : (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.-- : (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.-- : (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 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: (Part number begins with LSB2 or LSB4 for size 2 or size 4) (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 . 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.
