I recently did some pre season broadhead tuning. Several of my broadheads ended up passing through the target and smashing rocks and dirt. So i sent them in for replacement. I had damaged my 4 blade stingers, so i asked them if i could get them replaced with the 2 blade version so i would convert my stash of stingers to all 2 blades. I received them today. This warranty and wonderful customer service has converted me completely. I will shoot magnus products until i cant buy them anymore, as well as tell all of my bowhunting buddies about them. On top of it all, these are great broadheads to begin with.
