The UIAA equipment standard provides a baseline for equipment performance in a test lab under controlled conditions on new equipment. Although these test conditions are relevant to the conditions encountered climbing, conditions encountered at the crags and the condition of the equipment are equally important. This recommendation from the UIAA member federation The British Mountaineering Council (BMC) provides vital equipment information that is NOT explicitly addressed in the standard, particularly failure modes of the equipment and recommendations for the use, inspection, maintenance, and retirement of equipment.
Gemini
Description
The Gemini carabiner with Reactive Gate Technology eliminates the danger of the carabiner flipping into a bad alignment and cross loading while also providing the ability to open both gates simultaneously for ease of use and safety.

The Mad Rock Gemini is one of the most unique locking carabiners we have ever used, with two separate "chambers" accessed by two different gates, which both manage to lock with one single screw lock mechanism. While it works decently for belaying, it isn't super versatile for other applications. While we don't think it's a bad product, we would sooner recommend others for the purpose of preventing cross-loading.
