I would say that anything by HS is pretty much a scam, and probably not going to do much. Their products are pretty shabby and cheap.
The turkeys in my 'hood don't give a rat's left whisker about how pricey and pretty a hunter's calls are. That's why my vest has nothing but HS Strut friction calls in it!
I have completly fooled and lured many longbeards to their demise using them.
