My husband bought this for the golf course we play at. They are having a terrible time with geese. I had my reservations that this thing would work but 10 minutes into this thing being placed in one of the ponds those geese would not go into the pond. They were squawking and carrying on. Several hours later those geese were still spooked. The eyes in the unit are quite menacing in the sunlight. There is a heron at the course and we didn’t see her in the pond where the alligator was placed.

This thing has saved my fish. Not only has it saved my fish, but keeps the ducks and heron and any other large birds from my property and above ground pool ever since. I let it float on the water and the water is always moving via the waterfall or the fish swimming. 5 stars from me!
