Jeffrey R.wrote a review of Metolius Ultralight Power Cam Packaged Sets on May 7, 2010
First set of cams, new to trad
Used the larger cams on some trad routes in Colorado, didn't fall but they went in easily and the range finder made it easy to set. Used them also for building some top rope anchors and they held solid. Didn't move or slip at all and we all checked out the placements and thought they were great. I like these over C3's (haven't used C4s) the trigger mechanism feels more solid. I don't have to try to get these open, I feel the C3's took more effort.
