These work well however if your zero is high or low, you may hit the other bullseyes. I originally thought they were 4 separate bulls for pasting on cardboard. 4 on 1 has its advantages once you are zeroed and not hitting off the bull.
Pros: easy to apply multiple bullseyes
Cons: mult bullseyes on 1 page may result in confusing results
