To tell the truth, I've had one on my hunting bow for about 1 1/2 years now with not a lick of problems. Recently got a new bow and have had about 8 different drop-aways on it in the last month. Finally settled on a Trapdoor fora 3D setup. Yep, 8 rests in a month. But if I decide to hunt with this bow it's gonna have a ZE on it. Frankly, if the Trapdoor doesn't satisfy me or breaks down I'm still gonna have a ZE.
