Title: Could be much better
Review: I was very excited for this. In my childhood I used several whistles, having a super loud whistle could only be good for my family safety out in the mountains.I was wary because of the reviews stating that is not really that loud unless you really puff like a big bad wolf, well they are true, and worst than I thought.My 6 year old has issues blowing for a three seconds rescue signal.If I puff without really putting myself in it, is no louder than some cheap plastic party whistles out there.My 5 year old, constantly closes the chamber exits, so no sound for him if he is not really paying attention.In the end, not good as a security device.
