I have had multiple Turtle Box with the 1st gen and now 2nd gen. I have had issues along the way, but the Turtle Box team has been there to solve them every time in a very fast manor. I tell everyone that I meet about the speak and/or show them it in action!
From veteran hunting, fishing, or retreat trips Turtle Box always adds to the experience with a sound as if you were at a live concert... or in one case it was even used successfully to call wild game in! There's nothing this box can't do!
