I have a high ridge in my mouth and I’d given up on using a diaphragm. In order to get them to fit I had to bend them to the point of destroying the calls. A friend told me about Kluk calls and I ordered the starter pack. Since then I’ve ordered two additional calls and the high works great. It gave me another tool in my kit to try and fool an ole Tom.
Have not tried it yet...
Man this will be a new go to in the spring, great all around sound and performance.
Quality made. I bought the low and medium stretch and actually like both.
