- The trigger wire has a habit of popping out of the trigger bar.

Expert Reviews
- The non extendable Dyneema slings may require you to carry draws for some pitches.
- Very expensive.
- The semi-rigid stems make them less effective in certain situations, although they are overall easier to place because of the stiffness.
- Has a habit of wiggling while rope moves through it, unlike many other double axle cams.
Summary:
Everyone loves a good cam, and almost everyone loves the Black Diamond Camalot Ultralight. These cams are 25% lighter than their predecessor, the beloved C4, and they feel like it, particularly in the larger sizes. The decreased weight does not compromise on quality, and these are still durable pieces that hold really well during falls and are easy to place and remove. These are expensive, however, and the stiff stems may not be perfect for every placement, even though almost all reviewers covet the lightness and wish they could work in every crack.
