Another spin off of the original Carter Insatiable, the Insatiable 2 has an improved internal spring mechanism and an improved jaw and case arrangement that makes the Insatiable 2 one of the most advanced releases ever built. It practically melts into your hand so you can just forget about it and aim. Just stare down the X and let it do its thing. More than that the Insatiable 2 has been redesigned to include the new Carter Interchangeable Tension System making it easy to change the springs whenever, wherever you want.
