Summary: I got this for a middle school band piece that needed the "cartoon style" siren whistle effect. While not a cheap percussion accessory, it is definitely a quality instrument. Solidly built and works perfectly. It does have a plastic end with a completely metal body.
Summary: This is just a fun little whistle. It's not a loud alert whistle like some people seem to think. If you're stuck in the middle of the ocean you'll run out of breath before any passing ships hear this thing. It's more of a sound effect whistle like for cartoons (you've all heard it before).
Summary: The Acme Siren Whistle ordered THREE TIMES and received & returned to Amazon THREE TIMES was not the item pictured. The whistle pictured was ALL metal and those received had a plastic neck (as per item being reviewed) and not the ALL METAL whistle I ordered and paid for.
Summary: I didn't realize I needed an Acme whistle until I saw one on line. I use it mainly on bike rides to alert squirrels I'm coming through. Sometimes I blow it just for fun. It always evokes a smile. How many things can you say that about?
