I actually bought them to bring with me to Kansas on my hunting trip. I got them the day i left my house so I did not get to test them. I put them on a couple of my arrows. My first shot i missed a doe but the nock worked flawlessly. It was then when i noticed how easy they came out of the arrow. I had an arrow nocked and it was really windy out. The arrow actually became detatched from the nock while hanging on a bow hook. I decided that i will wait til i get home to use them. Once i can get them in my arrow securely i am confident they will perform as advertised.
