Have been hearing for awhile about the Hoochie Mama having some "quality issues". However, I have used mine since they hit the market and have had absolutely NO PROBLEMS with it.
As someone said earlier, it is limited in the sounds you can make with it but it is virtually "idiot proof". Very easy to operate and very effective.
At least the two bulls I harvested (and a couple dozen others called in, but not harvested) thought so, , ,
The Hyper Lip Single is the best call out there! Easy to use, extremely versatile in the sounds you can make (with practice), and loud enough to reach out there.
Finally, the Ivory Plate diaghram call is what I use to stop em at the final moment before the shot.
I own most of the other calls mentioned but have found these to be the BEST COW ELK CALLS. Get any of the Primos bow hunting for elk videos, listen to how they use the calls, and you will be successful.
