I had a 67#@27"Black Widow MAII blow up on me years ago. I was target shooting in my yard during the summer. I drew an arrow and POW! the upper limb let go and smashed me in the head.I didn't even know what the heck happened for a couple seconds,until the blood dripped in my eye. I called them up and they asked me to send the limbs back.They called a few days later and said that the glue hadn't cured right and what weight did I want my new limbs? Got them very quick and for free.
