I compared this with two others on Thingiverse. This one was second of the line-up. It's so loud and has a great pitch. I particularly love the warble effect from the double, it's very much a sports whistle tone. There's not a lot of resistance so it takes much less puff than say the V29 to get the same output. I love the design. It was pipped to the post by the compact emergency whistle, which is so loud and high pitched and needs less puff still to get going.
