Q2MD.

Shot the MZE and it is easy to put on and does what they say, butI just took it off and threw it in the box.Their is things I do not like about it, 1.had to shim quiver to use with it,2.too many moving parts. thought about Trophy Taker. I think the MZE is probably the best out their. With the overdraw attachment on it makes it more durable than most if you were to hit it. 3.The arm snags on stuff when walkimg through the woods. Looking to get rid of it.
