Of all the cams I have seen the DMM's have the best and most consistent color coding system. As was said earlier, they have the same sizing as the [b][url=http://www.rockclimbing.com/gear/product.php?p=311&list=1]Wild Country cams[/url][/b] which allows you to augment a set with the smallest 00 and largest 5&6. I have used mine for 4 years with no problems. The best thing about the DMM's for me is that they allow me to carry a large array of sizes with minimal weight, a full set weighs in near 2 1/2 lbs. Though the [b][url=http://www.rockclimbing.com/gear/product.php?p=305&list=1]BD cams[/url][/b] may have more range, barely noticeable in the small and medium sizes, they cost and weigh a lot more. When purchasing them consider also the matching [b][url=http://www.rockclimbing.com/gear/product.php?p=1868&list=1]DMM Prowire carabiners[/url][/b], they continue the color coding from cam lobe to trigger bar to spreader bar to carabiner and also weigh in at 36 grams yet are full size and full strength. The trigger bars do have an annoying tendency to slide down the wires when racked though with a little modification this is easily fixed. As far as trigger pull goes these are somewhere between the [b][url=http://www.rockclimbing.com/gear/product.php?p=305&list=1]BD's[/url][/b] (Light and smooth) and [b][url=http://www.rockclimbing.com/gear/product.php?p=4&list=1]Metolius[/url][/b] (moderately stiff and smooth).One more thing to add is that the cam stops are rated to 10 KN the same as most passive nuts. Overall I would say these are quality cams with great features at a bargain price well deserving of consideration.
