Have this binding on my Dynafit Broad Peaks and skied this setup from powder to steeps to 7000m peaks (about 30 days and lots of vert). I also used it a lot with ski crampons. Overall, everything works really well, ski crampons too. I like not having to bend down for switching the heel lifts.
Only 4 stars since on occasion during a traversing skinning on hard snow the heel flips to the ski position. Would buy again though.
