I received my Low D whistle today. It was a long trip to the Pacific Northwest of the USA. It arrived in excellent condition. After unboxing I began the search to find the flaw that made it go to the bargain bin. After a few minutes with no success I got out a magnifier and a high intensity lamp and began to search again. After a few minutes I found a shallow scratch about 1/32" long. That is amazing quality control. I highly recommend JDM. Now to learn the pipers grip. Well done JDM.
