I've tried it last year and it did okay. I shot a doe about 25 yards and one of the blades didn't open fully on impact.I tracked and found the deer 100 yards away with very little blood, the shot was perfect and hit both of the lungs. The entrance and exit hole looked liked what a 2 blade broadhead would of done. I don't know why it didn't open and I don't think I'm going to use it again. If you are looking for a mechanical broadhead, I would strongly recommend grim reapers, my bros have had great success using them.
