I originally got this as a bit of a novelty, but it's a much more real hold than I expected. It's just a little smaller than you're totally comfortable with so it ends up being this challenging knob that you've really got to trust yourself on. I'd recommend it for people looking for a good challenge and something that's not just another jug/sloper/crimp/edge, it's definitely different and quite a bit harder than you'd think and it's an excellent deal for the price. There aren't a ton of knobs like this out there, very cool.
