I have used mine last two seasons. Blind never got any response. Used on one two yr old I saw. He stopped but would not come. Used on yearling type passing by for fun he came in. as of yet,,not impressed. I do think where you hunt has alot to do with all these techniques. If bucks are calm,,not much suspicious, they work better. If area is heavy hunted,lots of disturbances,,bucks wary.
