Great skins. Easy to assemble and awesome performance in the field. I had never used skins before so my frame of reference is limited. I had to cut them to fit my skis and through the instructional video on Black Diamond's website and the provided instructions and tools, I was able to get this done properly. The clips on the back were easy to install and get to the right size. The first time I used them, things went great. I was out at Whitegrass in West Virginia and I got right up some steep slopes in iffy conditions. There wasn't too much snow stuck to the bottom (although I imagine this depends on conditions more than anything else), and I was able to take the skins on and off fairly quickly and easily throughout the day. Haven't had em long enough to talk about durability, but so far so good.
