I bought this whistle to replace another titanium whistle of a different brand which has is now broken. I have to say that the Nitecore version is louder, of higher quality and just looks better overall. I would highly recommend.

Great whistle

Brilliant

Very Nice product, smaller than expected. Very Happy :)

This is a great whistle. It's design is very sleek and looks cool. But practically is where it excels due to it size and weighing basically nothing! (4g roughly) As an aircraft engineer I carry around plenty of other tools/torch on my belt so this minimises any extra clumpy weight and doesn't take up a lot of room or get in the way. Performance great too as is deafeningly loud. Do a lot of mountaineering and orienteering too so very useful for this as well. Very impressed.
