My old whistle on my Chantal kettle stopped working and it was suggested that I should throw out the kettle. But I love the two-tone harmonica whistle. Interestingly, the website said that they were sold out but I was able to order one anyway.
Easy replacement and I love it.
For music lovers, the original whistle had an interval of a major sixth, the new one is a perfect fifth. So, while with shipping this was a bit expensive it is like having a new kettle!
