In my experience they shoot fantastic, I love the idea of the design, but I am not sold on them. The first deer I shot with one went a ways because I hit her in the liver but I had blood and a good exit so I was able to find her. The second deer I shot with one I hit high lung, had no blood, which makes sense due to shot location. The issue I had was the entrance and exit holes where the same size (unopened size). I am thinking the broadhead opened but the blades broke on the ribs on exit. I never found the arrow, but it took about 15 minutes for him to go down in about 50 yards from the location of the shot. So at the end of the day it did the job. Lastly I shot a coyote with one, I shot it behind the front shoulder and I believe it hit the opposite side front leg on exit. The one blade broke off and the other was bent. Never found the coyote and didn't find much blood.
