I would say that overally it is a well built rest, however you need to have the new designed upper arms (the ones with the brushes) and the new springy arrow support post.

Also depending on on the bow, you may or may not have good luck with it. For example, I was never able to get it to shoot well on my Trykon XL. No matter what I did, I always got a funky tear, however on my Protec it shot bullet holes with little to no work.
