I have been looking for a decent mouth call without breaking the bank and actually having a good quality sound. These here are amazing. I received my package in 2 days threw the double batwing in first and I was shocked it sounds amazing and really cuts through the wind great for windy days. I went ahead and bought the 4 pack and love all the calls. Great quality and sound plus amazing customer service! 10/10 from me keep it up Last Flight!
