Excellent Purchase
February 28, 2011

I have had a the older model of this biner for many years and loved it, worth every penny to me. But I wanted to upgrade to this keylock nose, and I'm so glad I did. I was just out using this biner last weekend and I love that every time I pull something out of it, it doesn't snag, something unavoidable im my older biner. Great one hand operation, very smooth. Heads up though... the biner may not be the same color as in the picture. Mine ended up being brown and orange, no worries though.

Pros: quick & easy to open, reliable

Easy to one hand operate

I haven't found any negative thing about this carabiner. It locks reliably, and it's easy to operate with one hand too. I didn't find three stage locking carabiners of other brands this easy to operate with one hand.
