I have had these skins for a year and have used them with my Volkl Kikus. They grip very well, though as expected, on icy, steep climbs, anyone on any skins will have a problem. Overall, on regular hard pack on steep slopes, they work well. Before you purchase, I recommend you check that the tip loop will fit your skis. I didn't purchase these from backcountry.com. Instead, I bought them at a local store and in the process noticed I needed a wider tip loop for my Kikus. As a result, I had to pay about $17 extra for two different tip loops that would fit my wider ski. It was annoying at the time, but I am very happy with the purchase. The wider tip loop also seemed to be a better choice than the standard loop that comes with the skis. Several people have also mentioned the tail clip coming off. This tends to happen from time to time with mine if I didn't tighten it enough or after several hours, but it's also an occasional occurrence with my friends' skins. Overall, I don't have a problem with the tail clip. I highly recommend these skins because they're sticky and reliable.
