anyone use the muzzy grasshopper?

I believe that is what it is called. it looks like 4 little wire claws that you put behind your broadhead to slow down the arrow. I was just curious if anyone has used them and their effectivness?

they look like little arrow stops to me, which everyone highly reccomends for turkey. i havent used them myself, but i do know that if the arrow stays in turkey it is ALOT better. can you use them with mechanical heads to stop the blades from opening all the way, creating much bigger entrance wound?
