Nice and Unique
I bought the 3 smallest sizes for aid climbing and I have not really used them that much. I would not really want to take wippers on the smallest size. They can be tricky to remove if heavily weighted because of the soft material on the "sliding ball". They are obviously great for small cracks and for podded out pin scars. They are definitely not my "go to" piece but a nice addition to a standard free or aid rack.
