I have one. Used it last year. Works great, and performs exactly like advertised. Will quickly bring you back to a repeatable anchor, and show any grip torque. If you use more than one pin, you simply line the yikes up with your lowest pin, the aim with your others. My brother was struggling with a peep, so I took pity on him and let him use the yikes, and put a no-peep on my bow (had one laying around). He ended up not using the yikes, so I'd probably be willing to sell it cheap if anyone is interested, e-mail me.

It really does work well, I think the only thing holding them back is they are overpriced to buy new compared to other peepless options... But I can save a guy some cash
