I Bought this recently and have not used it as I also bought a second hand Carter Insatiable and have decided to stick with that release for now as it feels better in my hand, it is the older model but was bought New and I have shot about a dozen arrows with it.
This release is
Ultra Sensitive there is pressure adjustment as well as trigger position adjustment, as can be seen it has the 360 degree Caliper Jaw head.
I am selling it to finance new arrows and would like £65 + postage, I would consider an exchange on a set of arrows in good condition 27 Inch + for a 60# compound with Hard Cams such as Nav 480 or 400 triples.
