Ryan Grimmwrote a review of DMM Dragon Cams - Anodized on June 4, 2011
When I saw DMM's announcement about these cams I was extremely excited to try them out. I've been satisfied with every piece of DMM equipment that I've used in the past and really wanted to see how much DMM could challenge Black Diamond. There is no doubt that the C4's are fantastic cams and I'm always happy to rack up with them. However, after almost a year of climbing with the Dragon cams, I'm a touch happier racking up with them.
So many things are similar between the two cams but two things really stand out in my mind:
1) Honestly, it feels good to support DMM and their commitment to their local workers. I'm not going to say much else about this as it has more to do with my morals than anything else. But if you value such things, it's a selling point.
2) The entendible slings. At first I wasn't really sure how much I'd use this feature, but when it's so convenient I realize how often I want more extension than you get with the C4's but less than you get with an alpine draw.
Are either of these reasons to replace a set of C4's with Dragon's? No. But, if you're looking to get your first or subsequent set of cams they are worthy of strong consideration.
