Doing the job well
these cams are very good. i think the three cam unit is a little more tedious to place than a 4 cam unit (master cams). But BD is high quality and they stand behind their products. i love the familiar BD color coding system. And the 000 is aid only - i am not an aid climber and always carry my 000. if it fits, i use it - better than nothing. and bottom line is they are rated higher than alot of the micro nuts i have, and that i will also place if they fit.
Overall, master cams may fit a little easier the first time in some placements. But these are great cams.
