Positive Reviews:

Loud, flat profile, works in water.

I compared four whistles and rated them by apparent loudness, how much force was required to blow, does it work if wet (in the water), and form factor.

-Windstorm All Weather Safety Whistle #84739
-ACR whistle Item #70110
-Whistle I had lying around similar to Carey and Co Safety Whistle Item #39665
-Survival S.O.S Whistle Item #84603

Windstorm All Weather Safety Whistle #84739
Incredibly loud - hurt my ears (blew it outside, not in an enclosed space).
Easily the loudest BY FAR.
Loud enough to get attention even if blown lightly - important for kids
(If you just breath lightly through this whistle it is as loud as some others)
Best bet to be heard over boat motors, shouting, waves, wind etc.
Less compact than other designs but easily the winner for marine activities or diving (works under water).
Downside is it is bulkier, wouldn't necessarily want to carry for non-marine use

ACR whistle Item #70110
Pretty darned loud (comparable or louder than hard blow on "classic")
Loud enough to get attention even if blown lightly - important for kids
Distinct 2 tone sound (sounds like a train whistle) doesn't sound like a "sports whistle" so it will stand out.
Nice flat design easy to tuck into PFD
Pea-less design works in water.

Carey and Co Safety Whistle Item #39665
Classic pea whistle. Like what any coach would use.
Very loud, but I suppose it doesn't work well in the water.
Needs harder blow to get good strong sound.

Survival S.O.S Whistle Item #84603
Absolutely horrible. Even blowing hard didn't generate enough sound.
Regular "coach's whistle" much louder.

Compact and Loud

This whistle is small enough that you can carry it in your pocket at all times and not even notice it's there. It's very loud, so it's great for signaling over wind and machinery, which is why I always carry it with me when I'm working too.

just right whistle

Excellent tone, not too loud, durable, compact, visible, low cost; my favorite whistle, I have extras to give as gifts as necessary.

Great bang for buck!

This is used as part of a "disaster bag" to be given to our Company new hires when they arrive.

Buy half a dozen!

Attach one to every PFD and give one to every kid hiking, camping, etc.

Neutral Reviews:

use for kids while in the woods

each kid gets one before they hit the trails, not as loud as I had hoped, may try a different brand

How do you mess up a whistle

I have not tried out in an emergency so I only blew into once. Inexpensive insurance I guess.
