Nite Ize Unisex's S-Biner Stainless Steel Slide Lock, Black, Size 4

Very rigid with nice little locks on the clasps. Perfect for the job.

Excellent product

Tried it out and it looks good and sturdy.

This product is good.

Perfect for what I need, light but sturdy.

We've had these S-Biners before, and not one has let us down. I particularly appreciate the locking mechanism, a simple slider that locks the S-Biner so valuable items cannot be stolen.The larger version (which I bought) will easily go over a bicycle handlebar. I chose the black painted version as it is less likely to corrode.Altogether an outstanding product that is built to last.

Looks nice and worked well at first, until one of the black plastic sliders that lock the clip into place broke.

Love this! Use it for my keys and to attach it to my belt loops when needed.It's used every day and so far there is no wear to the polish/coating even though it's metal-on-metal. The locks on each of the openings are easy enough to use one-handed and have been very secure. I am very grateful for this feature!For me this is the perfect size for a small bunch of keys and it hangs comfortably from my belt loop. Might get another one!
