They are good calls and David is a nice kid/guy. I am friends with him and he is making some great calls. He has been winning several awards recently with his pot calls. He is still going to college, but I don't think I will call him a kid again.
I have a glass, aluminum, and slate...all awesome calls...if i had to pick one..id get the glass or aluminum....His calls will scream if you want them too. Great buy for the money.
I have sent Him a Email and Left a Message on his phone but havnt heard back from him yet. Im a Competition caller and Hope he can help me up my Friction Calling.
