re: Anyone ever used the MOJO Mallard Machine?

You may have to anchor it. If it drifts into the other decoys it can be a major PITA. If it's windy you don't need it. Only hit it when they aren't looking. I've seen people get excited with them and they flared the ducks. If there is alot of vegetation in the water it can hang the prop up, especially in rice fields.
