No but I have killed a few feild turkeys without one
I think you'll get the ole "it depends" answer again. It's going to work sometimes.
One thing to note is how many kills they get to put that video together. I had the opportunity to talk with a pro film crew on a hunt a couple seasons ago. Asked how the new vid was coming and they said "pretty good. we have almost 70 kills for ther season between all the pro staff and film crews travelling around".
They get back to the editing room and pick 20-30 out of many more. They're trying to sell a new decoy and it looks cool so what hunts will they put on? Nothing wrong with it all. It's about entertainment and marketing but a DVD might not really be representative of a products actual effectiveness.
I've probably heard the story of gobblers turning and hightailing the other way with these decoys more. Again, that might be fine for you if you get that one time a season where a mature bird comes running in for a fight. Clearly that can and does happen sometimes.
