I have been using these skins for about three years now and they still work fine. I was worried when I first bought these that they wouldn't hold up as well as the asensions but I wanted something really light weight and small in my pack. So far I haven't been disappointed. I think I may need to reapply some glue but they seem to be staying on fine anyway because of the clip system. When they wear out I will def. replace them with the same skins. And my friends with the ascensions are thinking about getting these.
