I've got the Primos and it works good. Only use it when you know where you are and who's around you though. I had a HS Strut gobble call and couldn't get that thing to work for nothing. I think they have since changed the design to be more like the Primos and Quaker Boy calls though. Can't stress enough on knowing who's around you when you use one though. I am the hunter and don't want to be the hunted.
