| Black Diamond Oz Carabiner 4 out of 5 based on 8 user reviews.
 Cred: 1451 | | Review by Keese on Oct. 28, 2007 | | The Oz is the world's lightest carabiner. Thats all. If your racking lots of gear this could be the 'biner for you. |
| The Oz may be lighter than normal, however, it is also weaker than any other 'biner to come out this year. With a horizontal load strength of 20kn this is what Black Diamond calls new innovation. This author believes that lighter 'biners shouldn't be made at the expensive of their strength. |

| some people i've climbed with don't feel comfortable using these featherweight biners, but they are rated to 20 kN... they're strong. |

| Small and awkward to handle. The shape doesn't fit the hand well. Has the lowest breaking force of any production carabiner. |

| It's small, which may not work great for people with large hands. |
