Here's what other sites are saying:
DMM designed its AERO Bent Carabiner with a clean nose and a deep bent gate to make clipping and unclipping as simple as can be so you can cruise past bolts while you climb. This hot-forged carabiner is very strong for how little it weighs, and rope grooves direct your rope in the strongest spot for excellent longevity.
A brilliant sport climbing biner, the DMM Aero Straight-Gate carabiner is beefy enough to survive multiple dogging sessions and clips beautifully. A good size for all-round use.
The Aero has a solid bent gate to provide ease of clipping the rope. This curve in the gate means that it is easier to clip a rope in, meaning less time and energy spent when clipping and less chance of fumbling - meaning you climb harder. Sling not included.
