Well if Chuck Adams endorses it then it probably works. That being said it is just a higher tech version of a pendulum sight. I beleive there are other versions like this out, could be wrong though. I think I have seen a product simular to this by another company, but built much better. Even had the fixed pins and the pendulum type sight. I think it was savage, don't hold me to that though.

Looks kind of cheap and cheesy to me though, I don't know if I would want it on my bow.

I have never heard much about pendulums not working well, they are just noisy in most cases, I don't see this rest being much different. I would have to see one and look at before getting it. I sure wouldn't order one without holding it in my hand or seeing it mounted on a bow first.
