I never used or hunted with one until last year. I wish they would Outlaw them. I am hunting a new spot this year but where I used to hunt I was not getting nothing guys not far from me had 10 or 12 of the things did not matter what I did and I use to beable to call ducks off them all the time. I tried jerk lines too helped some but still was tuff. I got the robo duck and it was a little better but not compared to 10 or 12 of the things! Heck they quit calling at the ducks. I start calling and they would come close and see there wingers and bail right in over there. Got old quick so I tried to hunt days I threw they were not! But I moved to new spot and have no competition now.!
