I have killed a gozillion duck's using a Duck Commander. Its the person behind the call that makes the difference. Ducks have different voice tones and pitches like humans. I grew up on Moses Lake and would spend a lot of time by the water listening to duck sounds. That helped me call birds a lot. I would have confidence in just about any call (with in reason) to lure in birds. Most everyone blows way to much when working birds over decoys. Duck Commander calls are just fine, learn how to use it, and you will be happy.
