3.0 out of 5 stars Useful, but... May 13, 2010
Verified Purchase
Overall I like them and find them very useful. It's just right for keychain/pocket use. I am constantly adding and removing things from my keychain so I find a standard o-ring slightly cumbersome to use. It's quick and easy to snap open the s-biner and add or remove things. It will hold roughly the same amount of stuff as a standard o-ring and is fairly durable. Some of the black color is starting to wear off, but otherwise it's in good shape after 5 months of use.

The one glaring problem is that it's way too easy for it to accidentally pop open. There have been several instances where I've realized a key was missing. Luckily each time the key was in my pocket or right there on the floor. There is unfortunately no lock to keep it from opening accidentally. Either that or a stiffer spring would have made this a 5-star product. If you use the s-biner carefully it is a useful product. But if you have something of particular value, I would not recommend using it because you have a higher-than-average chance of something accidentally falling off.

2.0 out of 5 stars Not reliable November 29, 2009
Verified Purchase
I am feeling pretty good right now. Why? Because I am about to save hundreds of people the misery of losing their keys, favorite pocket knife, flashlight, thumb drive, etc... I have owned and used both the size 1 and 2 "S-biner"s on my keychain and they consistently (I was going to be ironic and say 'reliably') release/drop whatever is attached to them. I carry my keys in my pocket and have repeatedly found, on the ground, my $50 LED flashlight, 8GB USB drive, house keys, etc. I kept switching what I used the S-biner to hold thinking that it must be good for something because it is so cool. I even switched from size 1 to size 2. Finally after having that sick feeling of finding something I needed or that has value or was brand new on the floor about to be left and lost forever I gave up on this product. I give two stars because these actually are very nice, just not useful outside the safety of your home.

5.0 out of 5 stars Pick the right size, works perfectly May 3, 2012
Verified Purchase
Took me a while to figure out about all the sizes. I would recommend getting out a little tape measure and use these size measure's from the niteize website:
Size #.5 dimensions: 1.31" weight rating: n/a
Size #1 dimensions: 1.56" x .56" weight rating: 5 lb.
Size #2 dimensions: 2" x .88" weight rating: 10 lb.
Size #3 dimensions: 2.63" x 1.13" weight rating: 25 lb.
Size #4 dimensions: 3.5" x 1.5" weight rating: 75 lb.
Size #5 dimensions: 4.38" x 1.94" weight rating: 100 lb.

I got the #3 size, and i think that its the perfect size for my use. I have on there, a gerber Shard tool, a streamlight nano flashlight, 4 keys. all on the biner, without needing a keyring attached on there. For keys, i would think that the 0.5,1, or 2 might be a little tight. #4 is prob good if you have a jail warden-like set of keys, or if you want to hang a paintbucket from your pants (good luck keeping your pants on)

Only thing i don't like: One of my keys has the isosceles triangle shape for the ring hole and it because of its shape and the shape of the biner, it doesnt have any room to rotate around, making the rest of the keys sit kind of stiff. This is only an annoyance to me because i don't want to add on any key rings onto the biner, but obv. if you have a key ring that your keys hang from, its a non-issue.

This biner holds up pretty well, and im enjoying the s-design much more than traditional keychain biners. Why 5 stars? It does what its supposed to do, hangs on my beltloop nice and strong, easy to remove if i need it, and it holds a nice amount of weight.

4.0 out of 5 stars Handy May 29, 2009
Verified Purchase
I use them to attach my car key and micro tool to my main key ring. They are very hand but I do have one nit pick. I wish the tension on the wire gates were a bit more. Sometimes things unintentionally become unclipped because of the lack of tension.

5.0 out of 5 stars S-Biner: my nomination for Handy Widget of the Year October 5, 2010
Verified Purchase
Once in awhile you run into a small item that may seem unworthy of reviewing, but it's so handy that you come back for more. The Nite Ize Size-1 S-Biner is such a product.

First discovered these in a camera store in New Jersey one weekend after paying for my purchases, and they looked interesting enough to make me go back for a second look. I'm glad that I did, as they were my first ones. Since then I've purchased a number of them for various purposes, including here on, as I'll explain.

First some general observations on this interesting product. Had seen a small write-up in Backpacker Magazine in a doctor's office a couple of years ago where they gave it an Editor's Choice Award, and said: "Don't ask yourself if you need this useful little widget. The question is: How many?" I thought that is was an interesting comment and made a mental note to look for them... then promptly forgot about them until they were encountered in that camera store.

Since then I've bought a number of them, and have used these gadgets for attaching items to a rack on the back of my mountain bike, as a replacement for the junky carabiner on water bottle lids, as a handy belt-loop clip for temporary devices, and to attach a tripod to my photo backpack for quick release. The uses for these are only limited to your imagination.

The S-Biner is a small, handy thing that is a sort of double-ended carabiner, constructed from "2Cr13 Stainless steel for the body and 202 Stainless steel for the wire gates" according to the manufacturer.
