I'm sorry, the True Talker does have quality sound that is for sure however, I've owned 3, all 3 have fallen apart. [:'(]
I carry about 5 calls with me to the treestand, the two best in my opinion are the River Valley Game Calls Deer Flute and All Weather. I also have the Rubbernecker by Primos, A non brand call that has superior sound and a Woods Wise 6 in 1.
