Well, I cant really say if they work or not. Ive got a few but not had much luck. (luck is a figure of speach, no such thing as luck). I havent used a call in a few years. I think I do pretty good without them. I go out once or twice a week, and so far I got 29 squirrels. All I can say is give it a try, you never know till you try it. Let us know how it goes....
