Bests & Worsts Reviews from Amazon

I bought this because it claims loudest whistle. I will give it that is an extremely loud whistle if you're the one blowing it. My son and I tested it out on each other without the ear plugs that come with it. As soon as we got it we were excited, he blew first and I thought he was doing it wrong because it wasn't loud, But he claims his ears were ringing. So I took a turn and blew hard and sure enough my ears rang. It seems the sound bounces back to the blower. Now we were only mere feet from each other and the person not blowing had no effect. It's kind of gurgles out if you blow too hard. The air exits the whistle halfway through and bounces back. the tip of it is solid, not expelling any air or noise. Not for $11 I would not buy this again I would stick with the double barrel whistle as pictured. I don't have a decibel reading, but I'm very happy with the double barrel whistle.
