Nite Ize - LSB4-01-R3 LSB4-11-R3 S-Biner Slide Lock Carabiner, Black, #4

I loove it! Im never losing my keys again!

Hold my 30ft boat anchor well.

Great quality

Great for holding your keys

Marginal as a biner clip, the lock is worthless. Plan on losing keys.

Perfect to snap my water bottles on my backpack and not worry about losing them.

Fits nicely on my backpack shoulder straps, doesnt stick out like the regular hinge type. Intuitive lock, easy to use, looks sturdy.

The slide lock gets in the way more than it helps out.

Awesome

Perfectly suited for my needs.
