Sorry, No videos, but i believe it helps almost 100%. Iv never really did any damage wit it. I use the true talker and love it. Just yesterday i made it in the woods late because of school work, and because of this stupid time change the deer move early over by me, So as i was walking in to my stand i spooked a buck, pulled out the call, did a few short guns, kept walking did 1 more after 5 steps then walked a wase, Spooked him again..... so i did another grunt, made it to my stand, got up did 2 more and then he was back..... Ended up passing him up cuz he was just an 8point, but really helps wen u get busted.
