 Cred: 402 | | Review by jur001 on Oct. 28, 2007 | | This mini-biner is excellent for everything ( not to be used as a belay biner). I use it for setting up belays on multi-pitch routes, it's nose free so doesn't snag on every sling you have (like the quicksilver biner) - it is certainly worth the dollar. |

| Costs more than the quicksilver which is very similar except it does not have the toothless gate. |

 Cred: 8 | | Review by melham on Feb. 27, 2009 | | I use them for attaching to anchors with tethers, and they work great for me for this application. Easy to turn collar. Doesn't get stuck in anchor systems with narrow width and key gate. They replaced my BD Quicksilvers that I was using for the same thing and constantly getting stuck in the gate notch. |
| Easy to turn collar could (maybe) be vibrated or rubbed into the unlocked position under certain applications. |

 Cred: 881 | | My favorite locker. Its small and lightweight |
| there are lighter locker's out there like the trango, but this one just feels stronger and safer |
|
 Cred: 240 | | Super-smooth lock, keylock nose, light |
| A little smaller than I like for using a regular belay device (I use mine with my Cinch) |
|
 Cred: 233 | | Smooth action. Narrow, clean nose for anchoring into bolts. Very lightweight locker. |
| A little too misshapen for belaying. Best used as a general purpose locker. |
