### ⭐⭐⭐⭐⭐ Whither the Whistle You Want?  You've reached the end of your jaunt ;)
*by O***N on March 10, 2016*

Put it this way, I blew into it as hard as I could and three cats panicked and my wife gave me 'the look' and our son asked me to never use that whistle in the house again. They won't hear you if they're on the moon, but it's gonna' take a pretty big forest to muffle it. If a jumbo jet were flying five hundred feet above your head while you had this puppy wailing full boar, you most likely wouldn't hear the jet at all, but if someone else blew the whistle from five hundred feet above your head while a jumbo jet passed by your lips, no matter how hard you were blowing at the time, you'd likely hear the jumbo jet then, unless you're deaf or something close enough akin. It's plastic, but durable enough to whip it up against the wall, and to stomp on it with normal shoes without breaking it unless you whip it hard enough against a hard enough wall or stomp down hard enough I suppose for coal becomes diamond as oomph commands.Say you're being attacked by a carpet salesman in an alley somewhere, right? He's on you, talking about how you guys are gonna' have babies that are mostly human together, partially some other animals he has in his dna from experiments he tells you he will explain to you...'after', and he's already chopped off one of your hands, things are looking grim, no time for a tourniquet, you muster the maneuverability to put the whistle either in the assailant's eye socket, or nostrils, or into your mouth, and you blow it as loud as you can right by the aggressor's ear...not quite as effective as a grenade in his pancreas, but far more humane, and definitely enough to cause some damage and to perhaps disorientate him and scare him and shall grab the attention of many within the VERY wide earshot, relative to most whistles anyway, and or say you're kid is in the woods lost and you're looking for him because you thought for sure you could handle taking your family camping because you watched Jeremiah Johnson when you were a kid and later on, Into the Wild, and you were a boy scout, and your grandpa gave you a knife you never keep sharpened enough, and she or he is calling for you, only so many decibels and sometimes life and death hinges on a portion of a single decibel difference, muffled by the cave or not, just barely, depending on how good the hearing of the seekers might be as well but the point is this whistle helps you create more decibels than you can without it, though it takes some building up, like torque, like there's a ball bearing in it that swirls around due to wind flow and once it gets going fast enough and the flow is full force which takes about two seconds, it is LOUD, and maybe you hear a faint hint of a note, almost as if the last note in an opera being sung by someone on the other side of a mountain, only it's not, it's your kid blowing this whistle because you had the foresight, the courage, the wherewithal, the sagacity and the compassion to purchase it for her or him, because you go to investigate, and as you do, the noise gets louder and louder, and you're using yours to communicate back and you both keep using them as you get closer and closer until you get see each other and run in for that epic unforgettable hug of mixed emotions, because if you kept on blowing during the hug the tears wouldn't be just from joy, but also from pain.I plan to take the little silver ring off, cuz that part will shine in the light, and I have an all black outfit I wear around in canyons and for other occasions that this is a part of, as in this is in the belt I wear, along with lots of other stuff I got off amazon and tons of other places throughout life. There are so many advantages to a whistle, not the least of which is fun, that justify buying one, and as far as whistles go, this has it going on...is it the finest most durable most reliable loudest whistle ever...I highly doubt it, but it's well worth what they're asking for it, if you ask me, or perhaps, even if you don't, either way, tis what it tis, like snowflakes and fizz. In the Swiss Alps and on other mountain ranges in life throughout history whistling has been used by people far away from each other but not too far to communicate, when yelling doesn't cut it, whistling carries better than speaking, so if you're into that, you might want to get one of these too so you can add another peak or more between your sentries. Plus if you're a coach, or someone who uses whistles a lot, this is kind of funny because of how obnoxiously loud it is, as in prick, what did we ever do to you and why do you have to try and scare the kids at the starting line so badly they panic and collapse when what we're looking for here even more than for our own kids to win is for every one to have a good time? in short, it's a great time! get one. if you don't like it, I personally guarantee you I'll personally guarantee you at some point in the distant future that blue is one of my very favorite colors tied with lots of others...but my guess is, though you might not do a cartwheel after unboxing it to celebrate its glory, and to show appreciation for all it will do for you and your loved ones throughout your life, you will be very satisfied with your purchase and won't whine and throw it down and beat it with a hammer and curse life and amazon and retail in general and spit on it and wipe most of the spit off and then return it with a hate note and a frown face and lots of preaching about how integrity used to come first in salesmanship and excerpts about what used to happen to charlatans back in your day. let nike lead the way at least on this one...just do it.

### ⭐⭐⭐⭐⭐ Unexcelled
*by A***D on October 21, 2017*

This whistle is so loud that it is difficult to see what it sounds like without alarming people a block away. I was at a business visiting a friend, who wondered what I had around my neck on a lanyard. I explained. He said he was interested in getting one for each of his employees if it truly was as I had told him. So, we went out back---this is in a small business/light industrial area near an international airport---and sounded the whistle. I had not heard it before. It was so loud that is alarmed me and took my friend's breath away. People came running out of doors 200 and 300 yards away. We could do nothing but look around as if we, too, were surprised. My friend immediately went on-line and ordered whistles.The advertising says that this produces 120 dB of sound. When robustly blown, it is at least that loud, probably more---which I can say with confidence, having worked in situations where loud sounds had to be measured and evaluated. It is ear-splitting and just the right frequency to shriek and penetrate. The advantage of this whistle is that in most situations, it would be as effective as Mace, wasp spray, or other substances people typically carry for self-defense---even more so, because it would drive off all but the most determined thug without having to risk converting him into a homicidal maniac by a poorly aimed Mace blast. And, yes, a gun is more definitive in its action, but a terminal outcome, while perhaps justified, might have its own distressing consequences.This whistle is also a wonderful item to have in certain situations where attracting attention for reasons other than personal safety might be urgently needed. Breaking a leg in a rear parking lot where no one is around, for example, might be a real problem unless you could blow that whistle and have a crowd around you in seconds. Or, hiking with the family and getting lost would have perhaps a happier and more timely ending if whoever was lost could blow that whistle.Get one, or get several for family members, but don't test it without going to an unpopulated area, unless, of course, you are prepared to pretend that you also are surprised and alarmed at the impossibly loud and discordant sound when people come rushing out to see what happened.

This must be the loudest whistle on the planet. Keep one in my bug out bag, and another handy for easy access.
