Its been a week and i have shot most every day, they're still working. None have broken or flew off yet. If they lastat least 30 days per set then its great fer me. Y'all don't live wid the ducking deer. Bet awshucks knows what i am talking about. Ain't no arrow fast enough on a ducker, they hear and duck![]Its a southern deer thang, they attend class during the summer and use it in fall and winter!
