3inch Auto Locking Carabiner Clips, Solid D Shape Style, Heavy Duty Keychain Aluminum Carabiner - Holds a Maximum of 2698lbs, Lightweight 1.09oz, for Hammock, Hiking, Dog Leash Colors (Black, Pink)

Lock feature works well to keep it closed, but it is still easy to open.

Very well made and heavy duty !

I would use these for hanging my gear, but nothing vital. They feel a bit sloppy in the twist lock, though I must say they have never actually failed. Still, confidence in my gear is important. Good for the price range.

Love this product, strong but lightweight. The auto lock mechanism is amazing. No more twisting a knob to lock. So simple and easy to use.

Exactly what I wanted and needed

Nice idea and fairly decent execution. Use them to attach keys to belt loop. Keeps from having them stolen out or lost. A little too big and bulky but they do what I need them to do

Well built, lightweight and an easy to use lock mechanism.

Works effortlessly for connecting two dog collars in the event one breaks or comes unconnected. Easy on and off.

These seem very sturdy. The lock feature is handy to have and is easy to twist but not so easy that it comes undone on its own. Love the pink color too.

This was a really good product, however it was just too big for my purpose.
