Query: A good, budget friendly, well made whistle.

Well as other parents, I had to get this toy after my kids saw the slide whistle episode on Spongebob. It produces great sound and it is surprisingly well built for a whistle under $10.00. Highly recommended for kids for it's sturdy built. It will outlast the clumsiest of kids.
