Very strong retraction, holds to my pack very well. I like the clip, it makes it hard to lose nippers and hemostats.
Have a couple attached to my Aniak River Alaska bound waterproof sling pack plus another on a everyday sling pack and yet another on a compact chest pack. Easy on, easy off zingers that have all worked well. Another excellent Loon Outdoors product.
I attached my nippers to the zinger and it’s very handy.
Good quality. Like the S biner.
Bought two of these, one was fine the other blew apart attaching it to the bag. NOT robust.
