Review on Nite Ize Stainless Carabiner Separately by Shawn Reiter

These S shaped bins are well made. The overall feel is pretty solid and it doesn't feel cheap in any way. The locking mechanism is pretty stressful to unlock, but you probably shouldn't unlock them that often. The reason I do not recommend this product is that it is not used much in the real world. Because they are so small they can only be used for keys as shown in the photo. I thought they would be more useful for outdoor activities like camping, but it's difficult to put something inside to hang. I also don't see why you should spend $9 on a keychain unless you take the keys from them all the time. I'd recommend instead just getting a larger carabiner and a couple of those little loops. This way you can easily detach the buttons (if you really have to) and avoid the extra bulk that 6 small S-biners add. You save money and get a thinner key profile.
