Reviews
"I use them to hang light items in my garage, and to keep bags from sliding around in the back of my SUV."
"We used these as extra support on my kids' laptop bag shoulder straps (where they connect to the bag)."
"The only this I noticed is after time the lock gets really tight and may be hard for some to open up once it gets really tight."
"The one that I use on my keys get got worn out from the little key ring sliding around on it a lot, but I expected that to happen with any carabiner that holds my keys."
"I like the carabiners, but the package I received was missing one one of the locks on one and it was obviously returned by someone as it was stapled shut and had obviously been opened before."
"I use these for securing gear to my pack and for hanging gear at camp."
"Simple carabineers, useful for using to hook up simple, light weight things (like your keys, or a water bottle)."
"I'm not returning them, I'll most likely still use it for small things like water bottle clips."

Reviews
"I did originally look at using these to clip a gate shut in my back yard fence, but they're a little too thin up top to do that, but I also needed upgraded clips for my hammock and these seem like they'll fit the bill perfectly."
"We strung our hammocks with these in a recent foray into Zion National Park ... they worked perfectly."
"I was nervous, at first, about trusting a flimsy-looking wire gate to hold 240+ pounds of man and hammock, but that concern proved to be quite unwarranted."
"I plan to purchase more of these carabiners to upgrade my children's and for other odds and ends... like my keys!"
"I wanted a pair with a safety rating, although for this purpose, there is little to no weight to support."
"Great quality caribiner."
"Love the color (not that it matters for function, but I love blue) and they work great since I like to go camping with my hammock or just plain and simply take naps in my hammock."
"Been about a month and they still work!"

"I bought this after putting up with crappy "spring lever" carabiners that kept wearing out."

"I purchased these so I could clip handles to a suspension system I made for my home gym and they worked out PERFECTLY!"
"i use them to attach chute/water bottle or other item to different bags i have, so i wouldn't say i put these to any kind of rugged test."
"Great product."
"I love these things."
