Samuel J.wrote a review of Black Diamond Camalot Ultralight on May 19, 2016
I bought a #4 to see what these cams were all about--the weight savings are amazing (given the size of the cam). I would recommend these for larger sizes if you really want to save weight for expedition-type climbing. The core is no longer metal so the life of the cam is severely decreased opposed to a standard c4. The weight savings are definitely great for larger size cams #3/4 but I can't see a necessity for smaller cams unless you REALLY need to cut weight. The weight savings helped me stay under 50 lbs for my duffel with my trad rack, camera, tripod and rope which was very useful to save $$$ checking another bag. The cost is also fairly steep for said weight savings so I will echo that getting these over standard c4s is only if you really need them. So in short you are getting a lighter cam with a shorter lifespan for more money.
