Customer Ratings:

• omigoditsloud. Really, what else do you need to know? These whistles seem solidy built, are easy to see, lighweight and slim enough to clip to your PFD so that you don t even know they re there, and they are LOUD. Like, hurt your own ears just blowing them loud. I have to say that the person who reviewed them below and said that they only make a thin, raspy sound, probably did not blow FULLY into the whistle. You can t just toot these -- you BLOWWWW a full, long blast. Do that, and you ll peel the wallpaper off and attract plenty of attention. We bought ours for kayaking (the law requires them here in Florida)and haven t seen any better. A no-brainer. Four stars only because everything can t get five stars, or what s the point?
• Better Whistles from bottle caps. A raspy high pitched squeal would better describe the sound these make.
  Reminds me of trying to whistle blowing into a .22 Short casing.
  I will continue searching for a real, useful whistle.
  
• Yellow whistles. The whistles are perfect for a pocket because they are slim. Also, they are easier to see in semi-darkness since they are bright yellow.
  
  The only drawback was it cost a lot of money to ship an object so light and small. Shipping cost half of what the whisles cost!
