Whistle is way too loose.

The whistle screws in to change the pitch. They tell you to not change it once you find the correct pitch but the whistle is so loose it is impossible to keep it from moving. I attached it to my keys with the ring and lost the bottom half of the whistle almost immediately because it was so loose it unscrewed. Just don't bother with this thing as it is terribly made.
