6 for $20.00??!! "If it's too good to be true . . ." I'm not a big fan of aluminum in broadheads, Can get dented, scratched, gouged, and ultimatley throw things off. Just not right for penetration either. The blades (being hollow and thin: .030") look likely to shatter on bone and not do you much good.
Look, in most hunting seasons, how many shots on game do you get? Why take a chance on bargain equiptment? Spend $25.00 for three Slick Tricks and sharpen them, or hbuy new blades every year.
