I used them last season with sucess but got to see both ends of the spectrum. The first bird was either a small 2 year old or a very decent Jake, either way the pretty boy sent him running. He is kinda big. The next bird that came in was a Jake followed by a 3 year old bird that comensed to whoppin on pretty boy while purring the whole time

I sent an arrow through him

I used the real fan and in wind it looks killer with the deak moving around. I like mine facing me as well as the Hen. Sometimes a gobbler will get discouraged when he is strutting from behind and gobbling because the Hen and Tom decoys wont look at him so hell come on in to get in there face and get there attention. Deal sealed

I found that drilling a small hole in the top side of the Hen and using a strong wire stake with the tip bent over is way better that using a rock inside as suggested by knight and hale.
