When the strings of my Predator snapped it sounded like a shotgun going off in your face! After two times that was enough for me. My friend has a Barnett Quad 4 and I had been warning him about those bows but he said his has never given him any problems. I know he does not shoot much, so that was probably why. Well, he had a nice big fat doe come under his stand and when he went to shoot it the string blew up and he has no idea where the bolt went. He is pi$$ed.
