ArtCreativity Siren Whistles for Kids - Pack of 12, Durable Plastic Siren Noise Maker Party Whistles, Bright Assorted Colors, Birthday Party Favors, Piñata Fillers, Treasure Box Prizes

I bought these for one simple silly reason, to go to a Van Halen tribute show and blow it during the song Runnin' With The Devil. Now, I really have no reason to down rate these things, I didn't know what to expect and they seem to overall do their job. However, a tribute band handed me a siren whistle to blow during the song, that one in particular, the whistle lasted a bit longer. These, the whistle doesn't seem to last as long. It gets the correct tone for the song, but I wouldn't buy these for this particular song.

Daughter loved them for her bday party.

These little whistles barely worked. They were marketed for children and I doubt most children would be able to make any sounds - very quiet whistle. Unusable - had to throw them out. Disappointing and inconvenient!

Great product. Great buy

We used these during a boat parade. The boats could all hear us and they came closer to our home. We had a huge group of people all using their whistles and laughing at the same time. It was fun and helpful, especially for people that didn’t know how to whistle.

Faint sound. No consistent when blowing

I have a vintage whizzer from the 70's. Fantastic sound. Wanted to dissect these cheapies to make larger guage versions on a 3d printer. These are cute and colorful but they don't "whizz" like I was hoping for. No sustain. Totally different design from the originals. Giving them away next Halloween.

When we invite people with children we always give the kids some of these. Parent's usually take them away and play with them themselves. They're good and loud, and yes, will be annoying, but they're just fun!
