I havent heard of too many defective PSE bows comming off the line. PSE tests their bows extensivly.I have owned a PSE bow for 5 years adn will never buy another bow again. No other bow company has a warranty system like PSE. PSE will fix or replace your bow at no cost as long as youre not at fault. And sometimes even of you are at fault. Like bashing a coon in the head to get him off your leg and exploding your limbs. My wifes cousin did that three years ago and had new limbs shipped with in 24 hours to our local pro shop no questions asked. When he was done, he had new limbs, new cams, new cable and string, cost....0.00. His Mach 10 was upgraded to aMach 12. Now talk about warranties.
