Yes, it is a significant improvement over traditional carabiners with a notch. The keylock nose design ensures that your rope, webbing, or slings won't catch or snag when you are clipping or unclipping, which is essential for efficiency and safety during maneuvers.

While it is robust and reliable, the PerfectO is best used for specific tasks like rigging, connecting devices, or building anchors where a compact, oval shape is beneficial. Because of its smaller size, it is generally better suited for these specialized connections rather than as a primary carabiner for heavy-duty lead climbing.

Oval carabiners are symmetrical, which allows them to center loads perfectly. This makes them ideal for use with pulleys, ascenders, and other gear that needs to sit flat and stable, preventing the carabiner from shifting under tension.
