Rated 5 out of 5 by from Work for me I read the reviews about using these tiny s-biners for keys and I agree that they would NOT be good for that purpose. I bought them to attach my small camera case to my pack straps across my chest and find that they are terrific for that application. Much better than my previous connection which was a couple of webbing, buckle and split ring key holders. The s-biners are small, flat, almost weightless and attach/detach quickly and easily. It is obvious when the s-biners are secure (not always the case with the buckles in my previous solution). Because the case provides equal pull on the two s-biners, they cannot shift around enough to disengage accidentally, They work well for me.

Rated 1 out of 5 by from Worst. Keyholder. Ever. While I'm sure this product is good at other applications, DO NOT use it as a key ring! I bought four of these thinking they would be a good way to manage keys on my main Nite Ize key ring. Keys slip off the S-Biner easliy. Until today I've found the loose keys in my purse or on the floor of the car or in my bike pannier. But today I found my bike lock key on the sidewalk right under where I had left my bike locked up for several hours.

Rated 2 out of 5 by from Just OK - not secure The size is great and there is room for all my keys and key chain junk, but every once in a while a key jumps off. Lost a micro-flashlight already. Also, the finish on the wire gate leaves a very sharp point at its hinge that has scratched me twice. All this in only a couple weeks of use.

Rated 1 out of 5 by from Cheesy Quality Tension is very weak. Not fun when you expect things to hanging on your backpack when you get to your campsite. Sick to standard carabiners with strong closing power. Threw all of mine away after losing things that were hanging on them. Great idea, poor quality!

Rated 5 out of 5 by from Absolutely wonderful product. 0 complaints, works as expecte Absolutely wonderful product. 0 complaints, works as expected. They're definitely better than a regular carabiner with how easily you can clip in/out of them. I use these to easily hook in water bottles. Don't need a pocket for my Nalgene anymore!

Rated 5 out of 5 by from Great! A small unobtrusive way to attach/switch my ski pass between my severe weather shell to Spring skiing, mild conditions vest. I just stumbled upon it and REI and it was exactly what I needed!

Rated 5 out of 5 by from super S biner I bought these S biners to make it easy to change the "tab out " lines on my tent and they have worked very well and make setting up my tent much easier.

Rated 2 out of 5 by from keys pop out! The curved end of the latches allows my keyrings to pop out without knowing it. I've had someone return keys or my flash drive three times now.
