    Function

    Among the various tragedies that may occur every day, losing a key should be one of the more common, causing great frustration. However, with the whistle key finder, this tragedy can be prevented: simply attach the key to the whistle key finder's matching key ring. Then, whenever you can't find your key, blow a whistle loudly, and the whistle key finder will emit a loud engine roar to remind you of the location of your key. You can then follow the sound to find your key.

     Use

 You can turn it on normally (the switch is on the back, '-' is for on, '○' is for off), and it will respond to any sound without making any noise. It only reacts to whistling and various sharp sounds. For other voices, laughter, or everyday noise, it will remain quiet until it hears a whistle, and it can detect sounds up to 10 meters away!
